PETERSON GRABBER

A Peterson Grabber is used for bottom sampling. It has a two hinged

semicylindrical bucket that is held apart by a cocking device and is

released when the grabber hits the floor of the ocean

Peterson GrabberThe Peterson Grabber

has been used in fresh water to collect macroscopic fauna in sand, gravel, marl, or clay.

Is not intended for salt water sampling and must be painted with protection if so.

Secchi DiskThe Secchi Disk measures

the transparency of the water. The transparency of the water gets affected by the algae ,suspended of sediments, and the color

of the water.

Purse seine netDefinition-Net used in menhaden fishing

that encircles the school of fishWhat it does-Purse seine nets catch

schooling fish like tuna by en circling the school with a wall of netting. They can cap ture dolphins and other natural predators

feeding on the school.

Plankton NetPlankton Nets are a modification on the standard trawl used to collect planktonic

organisms, of any size, intact.

Plankton Nets have a long funnel shape that allows them to catch differently sized plankton.

There are 3 forms of plankton nets, which are The Ring Nets, The Bongo Nets, and the Multinet.

ConshelfDefinition: Continental Shelf Station Two was an attempt an environment where men could work/live on the sea floor.

An idea of what there underwater habitat looked like.

There were different stages of conshelf, i, ii, iii … and so on.

Elijah McClinton 1st period

Conshelf proved that human beings can live under the sea for long periods of time but that, even though they have the physical and psychological capabilities, humans are not made to exist in a world without sun. http://www.cousteau.org/technology/conshelf

CONSHELFIn 1962, Conshelf I was set up off Marseilles at ten meters depth. steel cylinder, 5 meters long & 2.5 meters in diameter.Conshelf proved that human beings can live under the sea for long periods of time.Conshelf II was essentially a small village, built on the floor of the Red Sea at ten meters depth.

Dredge an apparatus for bringing up objects or mud from a river or seabed by scooping or dragging. This helps the

rivers and seabed be clean .

Water Collecting Bottle

The bottles shown above are originally called niskin bottles and are used for collecting ocean water as a marine

census. These bottles either have one opening at the top or two, one on top and the other at the bottom. They are all put together to make on big CTD

that’s thrown into the ocean and collects the samples.

Water Collecting Bottle - Niskin

A Niskin bottle is a device for obtaining samples of seawater at a specific depth. Designed in 1910 by the early 20th-century explorer and oceanographer Fridtjof Nansen and further developed by Shale Niskin.

The AlvinUsed by the navy as a Deep Submergence Vehicle (D.S.V.) and used by Woods Hole Oceanographic Institution as a national oceanographic facility. Maneuverability tool used under the water at all depth making it easier for research. Its only down side is its 2 hour dive to the seafloor and 2 surfacing roughly giving you 4 hours of search time.

Side-Scan SonarA side scan sonar creates a picture of the seafloor. It measures the strength of how loud the return echo is and paints a picture.

Reversing ThermometerBy: Brian Galeano

Measures underwater temperature and pressure.“Consists of two mercury thermometers—one protected from the

water pressure and the other exposed—mounted so that they can slide up and down a cable lowered from a ship” (Britannica).”

When lowered to the depth to be measured, device called a messenger is dropped down the cable, the thermometers are inverted, breaking their mercury columns, and preserving their temperature readings as the device is hauled back on board ship.

Aluminaut Aluminaut was the world's first

aluminum submarine , built in 1964 . This contraption weighed in at 80-

ton, 15.5 meter manned deep-ocean research submersible was built by Reynolds Metals Company, which

was seeking to advertise the utility of aluminum

Underwater Camera

Underwater photography is the process of taking photographs while under water. It is usually done while scuba diving, but can be done while diving on surface.
