Toward lifelong visual localization and mapping
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2013-06)
Mobile robotic systems operating over long durations require algorithms that are robust and scale efficiently over time as sensor information is continually collected. For mobile robots one of the fundamental problems ...
Ocean Carbon and Biogeochemistry News, vol. 5, no. 3
(OCB Project Office, 2012)
Perry, MJ, E D’Asaro, and C Lee. An Autonomous Study of the Subpolar North Atlantic Spring Bloom — NAB08.
Timescales for the growth of sediment diapirs in subduction zones
(John Wiley & Sons, 2012-07-10)
In this study, we calculate timescales for the growth of gravitational instabilities forming in the sediment layer on the downgoing slab at subduction zones. Subducted metasediments are buoyant with respect to the overlying ...
Gene expression in the deep biosphere
Scientific ocean drilling has revealed a deep biosphere of widespread microbial life in sub-seafloor sediment. Microbial metabolism in the marine subsurface likely plays an important role in global biogeochemical cycles1-3 ...
Ice shelf-ocean interactions in a general circulation model : melt-rate modulation due to mean flow and tidal currents
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2012-09)
Interactions between the ocean circulation in sub-ice shelf cavities and the overlying ice shelf have received considerable attention in the context of observed changes in flow speeds of marine ice sheets around Antarctica. ...
Mechanisms behind the temporary shutdown of deep convection in the Labrador Sea : lessons from the Great Salinity Anomaly years 1968–71
(American Meteorological Society, 2012-10-01)
From 1969 to 1971 convection in the Labrador Sea shut down, thus interrupting the formation of the intermediate/dense water masses. The shutdown has been attributed to the surface freshening induced by the Great Salinity ...
Linking habitat mosaics and connectivity in a coral reef seascape
Tropical marine ecosystems are under mounting anthropogenic pressure from overfishing and habitat destruction, leading to declines in their structure and function on a global scale. While maintaining connectivity among ...
Horizontal density structure and restratification of the Arctic Ocean surface layer
(American Meteorological Society, 2012-04)
Ice-tethered profiler (ITP) measurements from the Arctic Ocean’s Canada Basin indicate an ocean surface layer beneath sea ice with significant horizontal density structure on scales of hundreds of kilometers to the order ...
Stratus 12 : twelfth setting of the Stratus Ocean Reference Station
(Woods Hole Oceanographic Institution, 2012-10)
The Ocean Reference Station at 20°S, 85°W under the stratus clouds west of northern Chile is being maintained to provide ongoing climate-quality records of surface meteorology, air-sea fluxes of heat, freshwater, and ...
Interaction of Ekman layers and islands
(American Meteorological Society, 2013-05)
The circulation induced by the interaction of surface Ekman transport with an island is considered using both numerical models and linear theory. The basic response is similar to that found for the interaction of Ekman ...
