A new study by National Science Foundation-funded researchers at the Woods Hole Oceanographic Institution and their colleagues found that freshwater runoff from rivers and continental s...
Tracking ‘marine heatwaves’ since 1950–and how the ‘blob’ stacks up
marine heatwaves blob stacks up
2016/3/30
Unusually warm oceans can have widespread effects on marine ecosystems. Warm patches off the Pacific Northwest from 2013 to 2015, and a couple of years earlier in the Atlantic Ocean, affected everythi...
Advances in Conservation Oceanography: New Tagging and Tracking Technologies and Their Potential for Transforming the Science Underlying Fisheries Management
Conservation Oceanography New Tagging
2015/7/3
Overexploitation of living resources and climate change are among the most obvious global-scale impacts of human society on marine ecosystems. In an age of such large-scale anthropogenic impacts, mari...
Framed-Quadtree Path Planning for an Underwater Vehicle with the Task of Tracking a Moving Target
regular grid framed quadtree data structure algorithm efficiency
2010/10/7
An autonomous underwater vehicle (AUV) must use an algorithm to plan its path to distant, mobile offshore objects. Because of the uneven distribution of obstacles in the real world, the efficiency of ...
Underwater multiple target tracking decision making based on an analytic network process
analytic network process (ANP) underwater multi-target tracking decision tracking logic
2009/12/25
Underwater multi-target tracking logic and decision (UMTLD) has difficulty resolving multi-target tracking problems for underwater vehicles. Present methods assume factors in UMTLD are uncorrelated, w...
An experiment to test the feasibility of tracking Gulf Stream rings with neutrally buoyant SOFAR floats was begun in September 1974. Three floats were launched at depths of 750, 1050 and 1080 m in a r...
Tracking a Gulf Stream Ring with a Free Drifting Surface Buoy
Gulf Stream Ring Free Drifting Surface Buoy
2009/3/7
A newly developed buoy which is free drifting and tracked by satellite was successfully used to measure the movement of a Gull Stream ring. The buoy, launched in a young ring at 36°15′N, 58°00′W, loop...
An Event in Water Exchange between Continental Shelf and the Kuroshio off Southern Japan：Lagrangian Tracking of a Low-Salinity Water Mass on the Kuroshio
Water Exchange Continental Shelf Low-Salinity Water Mass Kuroshio
2009/1/7
Low-salinity water masses were occasionally observed in spring and summer on the surface of the Kuroshio, south of Japan. Many of the masses were accompanied by excessive discharge of fresh water from...
Tracking Three Meddies with SOFAR Floats
salty Mediterranean Water SOFAR Floats Three Meddies
2008/12/30
Three Meddies were tracked for up to two years in the Canary Basin using neutrally buoyant SOFAR floats. These Meddies have cores of warm, salty Mediterranean Water and are approximately 100 km in dia...
Tracking Nonlinear Solutions with Simulated Altimetric Data in a Shallow-Water Model
Nonlinear Solutions Simulated Altimetric Data Shallow-Water Model
2008/11/11
Low-frequency variability of western boundary currents (WBCs) is pervasive in both observations and numerical models of the oceans. Because advection is of the essence in WBCs, nonlinearities are thou...
Tracking carbon flow in a 2-week-old and 6-week-old stream biofilm food web
carbon flow a 2-week-old 6-week-old stream biofilm food web
2008/4/21
We studied the carbon flow of an allochthonous carbon source (sucrose) in abiofilm food web using stable isotope analysis and lipid biomarkers. Initial biofilms were grown for 2 weeks in a third order...

Bed-roughness effects on boundary-layer turbulence and consequences for odor-tracking behavior of blue crabs (Callinectes sapidus)
boundary-layer turbulence odor-tracking behavior of blue crabs
2007/4/22
We employed laser-induced fluorescence (LIF) measurements of odorant plume structure and behavioral
observations to examine how turbulence affects the three-dimensional structure of odorant plumes an...
A new numerical technique for tracking chemical species in a multisource, coastal ecosystem applied to nitrogen causing Ulva blooms in the Bay of Brest (France)
tracking chemical species multisource
2006/4/30
A new numerical technique is presented that allows the tracking of any chemical element from any source in a
simulated foodweb, for instance assessing the proportion of these sources (river loadings,...
Spatial and temporal variation in trace elemental fingerprints of mytilid mussel shells: A precursor to invertebrate larval tracking
Spatial and temporal variation trace elemental fingerprints mytilus mussel shells invertebrate larval tracking
2005/5/8
Elements incorporated into developing hard parts of planktonic larvae record the environmental conditions experienced during growth. These chemical signatures, termed elemental fingerprints, potential...
