SECCHI DISKFunction: a black and white dish place in a river deeper and slower wave to find the depth when the disk vanishes.

Function: has a limited use. Not effective in clear rivers. The river current maybe require a extra weighted disk.

• Designed by Swiss scientist Auguste Piccard.

• Bathyscaphe or deep diving boat that was over 50 feet long.

• Consisted of gasoline which made it buoyant.

• Dove 37,000 feet into the Mariana Trench of the Pacific Ocean into the Challenger Deep.

a large net towed, usually by two boats, that encloses a school of fish and is then closed at the bottom by means of a line resembling the string formerly used to draw shut the neck of a money pouch or purse

Alcyone

The Cousteau Society's expedition ship. Concarneau, France, is her home port. Alcyone's success celebrates not just the wedding of hydrodynamics and aerodynamics. Marks the entry of electronics & computers into the maritime world. BY:AZAFF R.

• THIS BOAT HAS THE MOST MODERN TECHNOLOGY

• The engines take over automatically when the wind dies down, then they stop

completely when the wind is strong and from the right direction.

Core SamplerMathew Watkins

The McNeil Core Sampler consists of a cylinder that defines the portion of the streambed to be sampled and an attached basin that is used to store the collected sediments and trap the suspended fines.

A hydrometer is a instrument used to measure the gravity of liquids.

HYDROMETER

Hydrometer By Malcolm StokesPictures and function

Hydrometers measure the specific gravity of a liquid or the ratio between the density of the hydrometer and the density of the liquid being studied.

A conshelf is used to create an environment were people can live and work on the ocean floor.

DREDGE

A dredge is a tool used to scrape the bottom of the ocean to gather the sand and other things on the ocean floor to bring it to the beach.

WATER COLLECTING BOTTLE

Annissa ryals

Water collector bottles are also known as a CTD device that's used to measure the Conductivity (salinity), Temperature and Depth of seawater.

The water collector bottles also collect both data

on the properties of seawater and water samples in the Silver Niskin bottles.

Alvin

An Alvin is a Submergence Vehicle that lets you see in the bottom of the ocean.

Esveide Garcia

Built in 1964 as one of the world’s first deep-ocean submersibles, Alvin has made more than 4,400 dives and It can reach nearly 63 percent of the global ocean floor.

Alvin• Alvin is a deep ocean submarine owned by

the United States Navy and its operated by the Woods Hole Oceanographic Institution

• The deep diving submersible Alvin helped to turn a sunless, freezing marine world into a new frontier.

Side-Scan Sonar• Used to look at the

ocean floor and can give a detailed picture of a large area in a small amount of time as well as in any water clarity.

A reversing thermometer allows scientists to read temperatures in later point of time. It’s also used to register the temperatures in deep waters.

Reversing thermometer

When its turned 180 degrees (the mercury breaks in the special loop and will not get back together until reset, temperature at depth can be recorded with a 180 degree flip (as is done with the Nansen Bottle) and there will be no change .

Current Meter

Shaiera Gathings

Current Meters are instruments designed to measure the velocity of moving water in a river in order to determine its' discharge, also referred to as stream flow.

Current-meter discharge measurements are classified according to the type of equipment used and the nature of the station:

Wading measurement.Cable supported measurement.Bridge measurement.Boat measurement.Measurement through ice cover.

Flip: The FLoating Instrument Platform

FLoating Instrument Platform, whose great length lies mainly in the untroubled waters beneath the waves. As a result, she is almost as stable as a fencepost and, for those who study the sea, oceanographers, she offers an opportunity for more refined ocean measurements than they have ever had before.

Flip

Major Function

Tristan TullochP4

A Flip is use for stability and Soundlessness to detect underwater earthquakes and the sound of ocean creatures.
