Movie Clips:

	- M25_launch_movie (.mov) L. Madin, Woods Hole Oceanographic Inst. (WHOI) The quarter-meter MOCNESS has a 64 micron mesh for capturing smaller zooplankton forms such as foraminifera, radiolarians, and younger stages of many types of zooplankton, especially copepods, the world's most abundant type of zooplankton. This 'baby MOC' is only sent to about 200 meters depth. Like the other MOC's , it carries 9 nets that can be opened and closed by sending an electronic signal down the towing wire from the ship.
	- MOC1_launch_and_recovery (.mov) L. Madin, Woods Hole Oceanographic Inst (WHOI). - MOC1_launch_and_recovery (high-resolution .dv) L. Madin, Woods Hole Oceanographic Inst. (WHOI) The 1-meter MOCNESS has 335 micron mesh, a standard size for collecting typical zooplankton such as copepods, salps, and pteropods. This is the most commonly used MOC net system. It often samples to about 1000 meters depth. Progress is tracked on a computer on the ship as shown in this clip. The scientist can monitor the depth, water temperature and salinity in order to determine when to signal the nets to open and close. Once the MOCNESS is back on the ship, the cod-end bucket is removed from the net, poured into a pail and quickly taken to a cold room to help keep the animals alive. There, they are transfered to a tray for a snapshot photo record and experts begin examining the catch.
	- MOC10_launch_RHB06-03 (.mov) D. Lindsay, Japan Agency for Marine-Earth Science and Technology (JAMSTEC) - MOC10_launch_RHB06-03 (high-resolution .dv) D. Lindsay, Japan Agency for Marine-Earth Science and Technology (JAMSTEC) The 10-meter MOCNESS has a mouth opening of 10 square meters. Usually, this large net will have 3mm mesh nets to catch larger zooplankton such as krill, shrimp, and deep-sea fish. This particular system has specially designed nets of 335 micron mesh to collect the more typical zooplankton. This system was able to sample all the way to the bottom of the sea, about 5000 meters (over 3 miles!). Because life is sparse in the deep-sea, the large MOC is needed in order to filter huge volumes of water, on the order of a quarter-million cubic meters!
	- Gene_sequencing_RHB_06-03 (.mov) L. Madin, Woods Hole Oceanographic Inst. (WHOI) - Gene_sequencing_RHB_06-03 (high-resolution .dv) L. Madin, Woods Hole Oceanographic Inst. (WHOI) Once zooplankton are brought on board the ship, expert taxonomists identify the organisms and then the DNA team immediately begins sequencing their genes to create a DNA 'barcode' that could be used in future research to quickly identify these species. This clip shows a tray of vials, each containing a tiny bit of tissue from an animal, being placed into the sequencer and views of the graduate student at the computer with a display of the results of the analysis.

(WHOI) Meat-eating jellies, live zooplankton: 1. siphonophore gracefully moves through the water extending and contracting long stinging tendrils used to capture prey ; 2. ctenophore ('comb jelly') trying to 'catch' a stick offered by zoologist; 3. ctenophores with shimmering 'combs' that are tiny paddle-like blades that propel them through the water.
