Dr. K ATE BOSLEY (our NOAA/CCPO shared scientist), and I listedmutually beneficial tasks that Old Do-minion University and the NOAAOcean Service (then National OceanService) could accomplish under thesponsorship of the newly formed Na-tional Ocean Service/Old DominionUniversity Cooperative Institute forCoastal Physical Oceanography(CICPO). The last task included inthe Science Plan was “American PilotAssociation (APA) Training and Cer-tification,” a project particularly closeto Jim since it promoted safe naviga-tion, the main tenet of another partner-ship he had established with the APA.The workshop represented the finalevolution of that Cooperative Institutetask, as well as a goal of the APA/NOS partnership, so it was good tohear that NOAA wanted to host it atCCPO. It promised to offer the pilots“an opportunity to learn how NOAA’sNational Ocean Service provides navi-gation products and services,” and toshowcase the ability of CCPO to hostsuch a workshop on relatively shortnotice.

Norfolk office at Nauticus and relo-cated to Crittenton Hall. While atNauticus, Dr. Atkinson, Mr. Dixon,

“Could we hold the workshop atCCPO?” phoned JIM DIXON,NOAA’s Mid-Atlantic Navigationmanager, last March from his officeat Nauticus. He was referring to theupcoming three-day National Oce-anic and Atmospheric AdministrationProfessional Mariners W orkshopscheduled for about 20 participants,both marine pilots and instructors.The CCPO classroom normally ac-commodates five to 20 graduate stu-dents. During the training, a PC andInternet service would be needed atevery desk. Upon completion of thecourse, CCPO would arrange forcertificates for each participant,awarding Old Dominion UniversityCollege of Education ContinuingEducation credit. And, “Oh, we needto provide breakfasts and lunchesduring the class and also hold anevening social,” he said. LARRY ATKINSON, CCPOdirector, looked up at me and said,“Can we do it—10 days from now?”My mind wandered for a minute. I’veknown Larry for 36 years, and Jim for34. I said, “Yes.” Two and a half years ago I leftthe CCPO desk at the NOAA

systems whiz Dave W iden. As it turnedout, there were just enough PCs tocover all participants.

Jim Dixon guided the classfrom one topic to another, with the helpof NOAA Capt. John W ilder. One ofthe first “presenters” was our ownK ATE BOSLEY, who did an admi-rable job of covering NOAA’s PhysicalOceanographic Real-time System,PORTS©, an Internet-offered networkwhich displays real-time water levelsvs. predicted and other water and me-teorological parameters at major portlocations around the country, includingthe Chesapeake Bay. Kate demon-

strated her forecast/nowcast (real-timedisplay) model for the bay, namedCAFÉ.

The three-day course, high-lighted PowerPoint presentations ontides and currents, hydrographic sur-veys, Coast Pilot publications, nauticalchart production, and electronic charts.The pilots know all too well that themargins of navigation error are gettingnarrower with the advent of biggerships loading more cargo, trying tocatch the high tide with the maximumfavorable current for optimum commer-cial profit.

This workshop provided goodperspective on the efforts made byNOAA and other agencies, like theCoast Guard and Corps of Engineers, toprovide marine pilots with the bestnavigation tools available. Most valu-able were the advances in NOAAtechnology and navigation products.These products include: multibeam so-nar hydrography to detect hitherto un-known least depths, LIDAR (Light De-tection and Ranging), side-scan sonar,PORTS©, new additions to Coast Pilot(the bible of coastwise navigation),ENCs (vector electronic charts stan-dardized by the IHO), charts on de-

mand (raster electronic chartscorrected with up-to-date Noticeto Mariners publications andprinted on demand), and ASI, orAutomatic Ship Identificationsystem.While the training ran smoothly,

the weather produced rain for thefirst two days. Our evening so-cial, originally to be held outsideon the CCPO lawn, had to be heldin the Fireside Room. The “fingerfood” along with an emergencysupply of popcorn, kept the partygoing strong. The conversationwas animated, but eventually ex-hausted itself after a couple ofhours. In spite of a tight time-table, we definitely scored a hit

for the Center. On the third day, the sun came out.Lunch was enjoyed outside for a wel-come change at the Center’s picnictables, overlooking a calm LafayetteRiver. Group pictures were taken andall was well that ends well, except forthe cleanup. And, fortunately, it wasduring spring break, thus normal activi-ties were not disrupted too much. Thelast comments from the NOAA peoplewere, “Let’s do it again!”

as apprentices, act as mobile captains,bringing large vessels into the majorU.S. ports. The port pilot is a master atmaneuvering large ships into and out ofport, or to and from anchorages. He/she knows all the port rules and regula-tions, including U.S. Coast Guard Ves-sel Traffic Separation Scheme protocol,schedules of the port, and the prevalentnatural conditions of the waterway, i.e.,tides, currents, shoals, and weatherconditions. He even calculates waterdensity from the water temperature andsalinity in order to compute maximumcargo loads allowable given accuratepredicted water levels.

A marine pilot is requiredto hold a U.S. Coast Guard licenseas master of vessels of unlimitedtonnage. Maryland pilots fre-quently navigate container ships,tankers and freighters the lengthof Chesapeake Bay to the Chesa-peake and Delaware Canal, a dis-tance of some 150 nautical miles.The Navy has its own marinepilots for naval vessels.

NOTES from the Director..................This issue of Circulation gives you a taste of the broad range of activities occurring within thebrick walls of Crittenton Hall. The theme of “ Outreach” is something we all are asked to do andsome RFPs insist on it. Outreach falls in the education and service part of our triad mantra ofresearch, education, and service.

The lead article describes the challenge of providing a venue for a short course on safe navigationfor marine pilots. For years, I have tried to get more interaction between the commercial world,represented by the pilots; the academic world, represented by us; and the federal world,represented by NOAA. I have found that making this happen is not easy. Nevertheless, this springwe had real pilots from around the U.S. sitting in an academic research environment for a few days.We hope that their presence at CCPO will generate more understanding of the research world welive in.

The two enthusiastically written articles by Shannon Smythe and Ian Downie show the infusion of energy you get whenundergraduates and high school students enter our world. Their narrative suggests they did see the complexity ofoceanography and were intrigued by it.

By the way, these and other articles illustrate the article acquisition method used by Julie Morgan and Lydia Dalhke. Theyspot a likely candidate and, using hints of glory and some application of guilt, get an article. To the credit of CCPO

inhabitants, we have a tradition of willingly providing copy when asked.

ROSARIO SANAY is a graduate research assistantworking under the supervision of ARNOLDO VALLE-LEVINSON, CCPO associate professor. Rosario found the perfectmatch for two of her ocean-ography passions: pure sci-ences and the sea. In 1986,she enrolled in the School ofMarine Sciences at the Uni-versity of Baja California,Mexico, where she earned aB.S. degree in physicaloceanography. Wanting topursue her interest in re-search, Rosario later enrolledin the master’s degree pro-gram in physical oceanogra-phy at the Institute of MarineSciences and Limnology of the National University of Mexico(ICMyL-UNAM). There, she worked with Drs. Adela Monreal andDavid Salas on various projects. These projects introduced her tothe world of numerical models and gave her the opportunity toparticipate in several research cruises in the Gulf of Mexico. Shealso took part in research programs dedicated to the study of thecirculation and sedimentation in several coastal lagoons in Oaxaca,Mexico. Meanwhile, Rosario taught several courses in the hydrau-lic engineering program at Universidad Autonoma Metropolitana(UAM). Rosario earned her master’s degree in 1997 with a thesistitled, “Numerical simulation of the circulation of theChacahua-Pastoría lagoon system.” While working at UAM,Rosario met Eugenio Gómez, who knew Arnoldo Valle-Levinsonfrom their joint graduate work at the State University of New Yorkat Stony Brook. Eugenio introduced Rosario to Arnoldo. Aftertalking with Eugenio and Arnoldo about her interest in studyingcirculation in shallow water systems and numerical models,Rosario applied to the Ph.D. program at Old Dominion University.

In autumn of 1998, Rosario came to the USA to studygraduate-level physical oceanography under Arnoldo=s direction.At CCPO, Rosario has found a stimulating environment and plentyof opportunities to sharpen her research and field-work skills.During her time at CCPO, she has participated in research cruises inthe Chesapeake Bay (USA), East China Sea (Japan), Gulf of Arauco(Chile), Gulf of Fonseca (Central America), and Guaymas Bay(Mexico). She also participated in a U.S. Southern Ocean GLOBECcruise in Antarctica with CCPO professor EILEEN HOFMANN.Outside of life at school, Rosario enjoys running, reading, andcooking. Presently, Rosario is concluding her research on wind-induced and buoyancy-driven circulation on coastal plain estuar-ies, which includes observations and numerical simulations. Aftergraduation, Rosario would like to secure a postdoctoral researchposition in the USA and then eventually return to Mexico.

COLLABORATIVE EFFORT ON MODELINGHARD CLAM POPULATIONS UNDER W AY

The hard clam (Mercenaria mercenaria) sustains commercialand recreational fisheries and aquaculture production from the Gulf ofMexico through Cape Cod. At one time, the clam population in LongIsland’s Great South Bay produced nearly half the total coastwidelandings. This population has greatly diminished since reaching peakabundance in the 1970s. The definitive cause of these declines has notbeen demonstrated, but there is evidence indicating that early intensiveharvesting and recent occurrences of brown tide, Aureococcusanophagefferens, which affects filtration rate, feeding, growth andsurvival of larvae, juvenile and adult hard clams, have been factors.Environmental conditions, such as temperature, salinity, and phy-toplankton species and abundance, may have changed in the 1990s. Forexample, during the 1990s, mean winter water temperature in LongIsland’s south bays was 1º C to 3º C warmer than the long-term average.

As part of a research initiative to study the causes underlyingthe decline in hard clam populations, a team of researchers composed ofCCPO scientists EILEEN HOFMANN and JOHN KLINCK, alongwith Eric Powell and John Kraeuter from the Haskin Shellfish ResearchLaboratory, Rutgers University; Ray Grizzle from the University ofNew Hampshire; Monica Bricelj from the Institute for Marine Bio-sciences, in Halifax, Nova Scotia; and Stuart Buckner from the Environ-mental Control of Islip, NY, were funded by New York Sea Grant todevelop a mathematical model of the growth and development of the hardclam. The objective of the model is to evaluate potential effects ofvariations in biological and environmental conditions in the Great SouthBay portion of Long Island Sound on resident hard clam populationlevels and production.

Since funding began in March 2001, the modeling team has metseveral times to work on the hard clam growth model. The result is aworking model for an individual hard clam that includes effects ofenvironmental variability and brown tides. One unique aspect of themodel is that changes in weight and length of an individual clam arerelated to the condition of the animal. The rationale for using a length-weight-condition coordinate system for the hard clam model is that itallows growth to be defined as a function of animal condition rather thanas a function of animal weight. Thus, changes in condition dictatewhether or not the clam can increase length. This approach ensures thatclam weight and length remain coupled during a simulation becauseweight can change without requiring a corresponding change in length.As a result, the clam will not exceed realistic length-weight combinations.This approach represents a change in the way that growth models areformulated for clams and potentially for other bivalve species.

The results of the individual hard clam model are scaled to thelevel of individual cohorts, which is the group of young individualsproduced in a year, by including probability distributions which allow arange of outcomes to be simulated for a given set of environmentalconditions. The surviving larvae provide the basis for a yearly cohort.Continued simulation for several years results in initiation of multiplecohorts, which then represent the hard clam populations. The outcomeof the simulations can then be compared to observed length frequencydistributions for hard clam populations.

The hard clam model is now being used for simulations tounderstand the effects on hard clam growth and reproduction of: 1)biological factors, such as variations in respiration rate, 2) brown tides, 3)climate and environmental variability, and 4) fishing and natural mortal-ity. The first results from the simulations were presented at the NationalShellfisheries Association Meeting in April 2002 and more presenta-tions, as well as publications, are planned for the future.

IAN DOWNIEIAN DOWNIEIAN DOWNIEIAN DOWNIEIAN DOWNIE

I owe much to the science of all things wet. Lastwinter, my oceanography teacher, Michael Bates ofMaury High School, invited me to participate in a state-wide oceanography competition called the “Blue CrabBowl.” Mr. Bates had been planning to compete in thisbowl for quite a while and had already formed a team ofhis brightest students (of which I had not been originally apart). Luckily for me, and perhaps for the whole team,one of the team members had to drop out at the lastmoment, and so I was invited to participate in her place. Ihad a less than adequate amount of time to prepare and Idid not even know for sure whether I would be able toattend the bowl until only a week before it was scheduled.The Blue Crab Bowl’s host this year was Old DominionUniversity and going there gave me my first look at thegrounds, which were magnificent! The architecture andfloral planning were quite appealing, but back to thesubject at hand.

When the Maury team gathered early on thatpristine Saturday morning of the bowl’s beginning, it wasnot overly difficult to become wrapped up in the excite-ment of the competition! Only the schools with thebrightest and most clever students would come out thisday, and we were to spar with them in a rigorous mentaltournament! Along with our anticipation and excitementcame their evil twins, doubt and hesitation. These were tobe our greatest foes, but nothing could stop us! We feltinvincible this day!

Ironically, the first team we played was fromGrafton High, the team that would eventually go on tobecome Virginia’s state champions! We tried valiantlyagainst this powerful team and the victory would be theirs,but only by a single question! We went on to other gamesand were eventually eliminated from the tournament, butwe had done far better than any of us had ever hoped forand we went home with pride.

The skill and intelligence possessed by theMaury team has done much for me, and I hope as muchfor the other members as well. One of the perks of doingwell in the bowl was the placement of myself onto nextyear’s Maury Blue Crab Bowl squad as team captain!Another was an offer (which I accepted very willingly) for asummer internship in Old Dominion University’s Ocean,Earth, and Atmospheric Sciences Department! I am nowcurrently working under CCPO associate professor,ARNOLDO VALLE-LEVINSON, assisting him in anongoing project on local waterways that has been in placefor almost two years and counting. Oceanography hasdone much for me, and perhaps one day, I may be able todo as much for it.

My journey to a summer internship with ARNOLDOVALLE-LEVINSON, CCPO associate professor, began, ap-propriately enough, in water. A chance meeting in a hot tublast summer led me to meet Jan Smith, the Director/Liaisonfor the Old Dominion University Career Management Centerfor the College of Sciences. Jan gave me a tip about aninternship with Arnoldo, doing oceanographic work during thefall 2001 semester. Since I am majoring in oceanography formy B.S. degree, I jumped at the opportunity, applied, andinterviewed with Arnoldo. Understandably, he wanted some-one with better math skills, so he hired another applicant. Iwas disappointed, but was later happy that I was not workingwhen finals and deadlines came up. Next semester Arnoldooffered me the job , but I had already made too many othercommitments to work for him. Finally, at the end of the springsemester, with more help from Jan Smith, I applied for, andwas awarded, Arnoldo’s summer internship. After my finalswere over, I started working on data Arnoldo had collectedfrom the mouth of the Lafayette River.

Trying to learn IDL, UNIX, oceanographic terms andconcepts, and refreshing my math skills all at the same timewas initially overwhelming. After a few weeks, things startedclicking for me and I surprised myself with how much I waslearning about programming. IDL’s power to perform thou-sands of calculations on data and graph them in under 30seconds amazed me. Learning there are five main tidalconstituents operating on a body of water was an eye-opener.The cruise on the Chesapeake Bay I participated in surprisedme with how much patience was required, but it was not toohard waiting for the next CTD cast surrounded by the beautifulbay.

My moment of triumph came when I finally ironed outall the bugs in my first program and looked down at theresulting graph of water flow over four months. I wasintroduced to the Conservation of Momentum Equation byhaving to calculate and graph its components for one of thedata stations. It is difficult to measure the extent of what Ihave learned because it has been such a gradual process.Arnoldo and I joked that I should be paying him tuitionbecause I was learning so much! Taking the Oceanography306 course in the fall should be easy, at least. Arnoldo andeveryone in the CCPO building were extremely helpful to meand I really appreciate that. While I am still very interested inthe biological oceanography track at Old Dominion University,I realized this summer I like physical oceanography verymuch. If I can somehow do a double track, it’s possible Icould supplement the intense computer modeling of physicaloceanography with some outdoor field work in biologicaloceanography.
