A B

C D

3 Which of the following is NOT an accurate description of coastal waters:

A They are euryhaline & eurythermal

B They are relatively shallow & adjoin continents

C They are isothermal in the midsummer & midwinter

A Cadmium

B Lead

C Petroleum

D Mercury

5 The earliest recorded sea voyage was by the

A Egyptians

B Greeks

C Phoenicians

D Polynesians

6 All of the following are adaptations for plankton dealing with the viscosity of water EXCEPT:

A Warm-water copepods have many appendages

B Many plankton have a small surface area to volume ration in order to maximize the buoyant force of water

C Many plankton produce a small amount of oil to help keep themselves lower in the water column

D Cold-water copepods are more hydrodynamic

7 All of the following zones are aphotic EXCEPT:

A hadal

B mesopelagic

C bathypelagic

D abysopelagic

8 The largest ocean garbage patch can be found in the:

A Atlantic Ocean

B Pacific Ocean

C Arctic Ocean

D Indian Ocean

9 The Phoenicians

A invented the compass

B where the first to drill for oil

C stayed within sight of land while on the water

D invented fish hooks

10 Which of the following is FALSE when considering coastal wetlands:

A They are ideal locations for larger predators to hunt

B They can be found in low & mid latitudes

C The water is considered brackishD They are defined as saturated areas that

border coastal environments

11 Bioaccumulation can be defined as:

A The amount of energy that is retained with each increasing level of the food chain is only 10%

B 90% of the energy from the lower-levels of the food chain is l ost to the environment as thermal & other forms of energy

C A substance building up in the tissues of organisms and increasing in toxicity up the food chain

D A substance building up in the tissues of higher-level organisms & causing a toxic trickle-down effect on lower-level organisms

12 An organism that survives by being part of the deep scattering layer (DSL) would most likely be found in which of the following zones:

A Hadal

B Epipelagic

C Euphotic

D Bathypelagic

13 All of the following are reasons why coastal waters are disproportionately effect by pollution, EXCEPT:

A They are relatively shallow, so pollutants are more concentrated

B They are better circulated than open ocean, so more pollution is draw in

C Sources of both chemical & thermal pollution are often found nearby

D They are heavily used by humans for commerce, recreation, and fisheries

14 Which of the following is FALSE when considering petroleum-based pollution:

A Petroleum is biodegradable, therefore is not considered to be highly damaging in comparison to other pollutants

B Petroleum will stay on the surface of water

C Petroleum spills mainly effect low-level creatures, such as phytoplankton, that rely on sunlight for survival

D Petroleum spills have a longer-lasting effect on fully aquatic organisms such as fish than semi-aquatic organisms such as gulls & terns

15 All of the following are known to have a negative bioaccumulating affect EXCEPT:

A Nitrogenous byproducts from fertilizers (TAN)

B Mercury (Hg)

C Polychlorinated biphenyl

D Dichlorodiphenyltrichloroethane (DDT)
