Propulsion optimization for ABE, an autonomous underwater vehicle (AUV)
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1991-09)
The oceanographic community is moving towards unmanned autonomous vehicles to gather data and monitor scientific sites. The mission duration of these vehicles is dependent primarily on the power consumption of the ...
Development of an integrated economic and ecological framework for ecosystem-based fisheries management in New England
We present an integrated economic-ecological framework designed to help assess the implementation of ecosystem-based fisheries management (EBFM) in New England. We develop the framework by linking a computable general ...
Sensitivity analysis of periodic matrix population models
Periodic matrix models are frequently used to describe cyclic temporal variation (seasonal or interannual) and to account for the operation of multiple processes (e.g., demography and dispersal) within a single projection ...
Corals record persistent multidecadal SST variability in the Atlantic Warm Pool since 1775 AD
(American Geophysical Union, 2012-09-29)
Accurate low-latitude sea surface temperature (SST) records that predate the instrumental era are needed to put recent warming in the context of natural climate variability and to evaluate the persistence of lower frequency ...
Anisotropy in high-frequency broadband acoustic backscattering in the presence of turbulent microstructure and zooplankton
(Acoustical Society of America, 2012-08)
High-frequency broadband (120–600 kHz) acoustic backscattering measurements have been made in the vicinity of energetic internal waves. The transducers on the backscattering system could be adjusted so as to insonify the ...
Improving HF radar estimates of surface currents using signal quality metrics, with application to the MVCO high-resolution radar system
(American Meteorological Society, 2012-09)
Estimates of surface currents over the continental shelf are now regularly made using high-frequency radar (HFR) systems along much of the U.S. coastline. The recently deployed HFR system at the Martha’s Vineyard Coastal ...
A new US polar research vessel for the twenty-first century
(The Oceanography Society, 2012-09)
Scientific and political interests at the poles are significant and rapidly increasing, driven in part by the effects of climate change and emerging geopolitical realities. The polar regions provide important services to ...
Fish otoliths in superficial sediments of the Mediterranean Sea
Otoliths represent a significant biogenic carbonate component in marine sediments that may provide valuable information for paleoenvironmental and biogeographic reconstructions. In spite of their importance, relatively ...
Absolute probability estimates of lethal vessel strikes to North Atlantic right whales in Roseway Basin, Scotian Shelf
(Ecological Society of America, 2012-10)
Vessel strikes are the primary source of known mortality for the endangered North Atlantic right whale (Eubalaena glacialis). Multi-institutional efforts to reduce mortality associated with vessel strikes include vessel-routing ...
