[1] We assessed interrelations between climatic, meteorological and hydrological factors in the Balearic Sea, and identified drivers of the abundance variability of planktonic copepods over the period 1994–2003. Temporal variability in the total abundance of copepods appears to be indicative of the southern spreading of the Northern Current, and therefore of meridional transport of water masses...

In situ measurements of surface chlorophyll and zooplankton concentration are compared with in situ hydrographic measurements and infrared satellite images of the west coast of British Columbia for early winter and midsummer study periods. Maximum winter concentrations ofchlorophyll (1.0 mg m-3) and zooplankton (2900 counts m-3) were found in colder, more stratified nearshore water. Warmer wate...

We investigate the potential of strategic ship routing through dynamic currents derived from satellite altimetry by simulating current patterns in a dynamic Gulf Stream region to reflect present and improved current estimation capabilities, using dynamic programming to determine approximately 3-day routes through the current patterns, and estimating relative fuel savings that would be obtained ...

Digital hydrographic maps have transformed global environmental studies and resource management. A major database update will provide even clearer more complete views of Earth’s waterways.
