TL;DR: In this article, the advantages of using unmanned underwater vehicles in coastal ocean studies are emphasized and two types of representative vehicles, remotely operated vehicle (ROV) and autonomous underwater vehicle (AUV) from University of South Florida, are discussed.
Abstract: The advantages of using unmanned underwater vehicles in coastal ocean studies are emphasized Two types of representative vehicles, remotely operated vehicle (ROV) and autonomous underwater vehicle (AUV) from University of South Florida, are discussed Two individual modular sensor packages designed and tested for these platforms and field measurement results are also presented The bottom classification and albedo package, BCAP, provides fast and accurate estimates of bottom albedos, along with other parameters such as in-water remotes sensing reflectance The real-time ocean bottom optical topographer, ROBOT, reveals high-resolution 3-dimentional bottom topography for target identification Field data and results from recent Coastal Benthic Optical Properties field campaign, 1999 and 2000, are presented Advantages and limitations of these vehicles and applications of modular sensor packages are compared and discussed

TL;DR: In this paper, the authors used the NOPP project to expand the operational capabilities of the autonomous underwater glider, Seaglider, to extend its measurement capabilities to include biogeochemical variables, specifically dissolved oxygen, phytoplankton biomass, and suspended particle concentration.
Abstract: : The primary objectives of the overall NOPP project were to expand the operational capabilities of the autonomous underwater glider, Seaglider; to extend its measurement capabilities to include biogeochemical variables, specifically dissolved oxygen, phytoplankton biomass, and suspended particle concentration; and to demonstrate the power of this new autonomous mode of ocean observing. Seaglider can operate in both a transect mode or a station keeping mode. It moves horizontally and vertically using buoyancy and wings, diving as deep as 1000 meters, and transmitting data at the end of each dive cycle via Iridium satellite phone. The key to Seaglider's ability to operate continuously for many months at a time is its efficient hydrodynamic shape. The development of the biogeochemical sensors was guided by the need for these sensors to be unobtrusive to minimize drag, small to conserve space, and power stingy to maximize battery lifetime. The specific objectives of the past year were to demonstrate the capability of Seaglider to maintain a persistent presence in waters off the coast of Washington State, USA, and to interpret the optical and chemical data collected by Seaglider in context of a four-dimensional view of ocean biogeochemistry.
