Midwater Ecology

Midwater ecology is a special way of saying “looking for unknown species and organisms”. In the middle of all the oceans there is a abyss, the

researchers of MBARI look at cameras and graphs inside these abyss’s. They always haveResearchers on the cameras or making graphs.

These are three regular midwater fish

and a snipe eel.

Studying midwater is very important because of the rising sea waters or changes in the currents of the oceans, also to discover and decide what species life spans are; They also help with measuring oxygen levels in the sea. The measurement of oxygen can help with seeing what cells and living organismslive or can reproduce in a certain area of the sea

Why Study Midwater Ecology?

The R.O.V. Is a specialized vehicle to look under water.

Remotely operated vehicles are robot submarines that are tethered to a ship and are controlled by workers called “pilots”. The robot has features like; arms for grabbing and moving, high definition cameras that record sea life, ocean floor and shifting objects. The robot also has sensors to detect the sea floor and mapping it. These remotely operated vehicle is made of a strong but light weight frame to support itself. The long tethers are wires that connect sources in and out of the ship. If the robotwere to sink or break while in the water there is anEmergency air system to bring the robot to the top.

This robot is ROV Doc Rickets at MBARI

The engineers at MBARI look off of this robot to graph information

The collection of data from the ROV is collected and gathered in the MBARI lab to see what how marine life works. The robot gathers data about the sea water, sea floor, and sea life that they can graph what effects the sea. Some of the missions of the robot have found a lot of data showing that there are hills and valleys on the sea floor. Some of the info also has data showing that iron in the ocean is low enough to effect krill. When the reachers graph they always have to double check everything that they graph.

Graphing the ecology of living organisms.The researchers at MBARI graph the date from the robots and graph it on a paper sheet which they look at contently. MBARI help local and international fisherman see what fish are in danger and which ones are overpopulated or even invasive. This fish on the chart has been graphed by MBARI for a years and it will show how iron and humans effected their habitat. The catchers in the Atlantic ocean look at this cart to see what and when the fish are in danger.When looking at these chartsMBARI can look what the pat-tern is. The population and The catch rate is going downSo that will tell what the dataOver the year have collected.

There are many organisms that are found each year.

There are many organisms found each year on the midwater ecology expedition at MBARI. The pilot’s or people who look at information on camera look for new and strange patterns in the sea floor or sea levels. When the pilots look at graphs and sea levels they make sure that they don’tmiss a organism. The camerason the ROV have HD so the data is not missed.
