Design Of A Gas Tight Water Sampler For Auv Operations, Christopher Roman, R. Camilli
Christopher N. Roman
This paper presents the design and preliminary test results for a small gas tight water sampler intended to work on scientific AUVs. In recent years AUVs have developed into reliable platforms capable of carrying a wide variety of environmental sensors for in-situ chemical measurements. Physical sample collection however remains difficult, due to the combination of space, power and complexity constraints inherent in working with autonomous platforms. The AUV sampler is a small (12 cm times 85 cm) cylindrical package designed to collect eight 20 ml gas tight volumes of water, with each sample maintained at high pressure to depths of …

Seawater and sediment from the Florida panhandle coast were assayed for a panel of 28 organochlorine insecticides and PCBs. No samples exeeded the detection limits of the analytical technique, which were well below levels reported for other ocean locales. Organochlorine levels in this area of the Gulf must be very low. This does not preclude their biomagnificatioon up the food web.

Abstract Seawater and bottom sediment from two areas of the Gulf of Mexico near-shore waters along the Florida panhandle, one near Panacea (South of Tallahassee) and the other, St. Joseph Bay, about 100 km to the west, were analyzed for organochlorines (OCs). The first area is contiguous with the open water of Apalachee Bay and receives significant fresh water inflow. The second is a long, narrow bay with a north-facing mouth adjacent to the mainland and little fresh water inflow. Samples were analyzed for a panel of 28 OCs including several insecticides and metabolites as well as hexaxhlorobenzene and total …
