Comparing the hydrography and copepod community structure of the continental shelf ecosystems of Washington and Oregon, USA from 1998 to 2009 : can a single transect serve as an index of ocean conditions over a broader area?

Creator:

Lamb, Jesse F.

Abstract:

Bi-weekly sampling of zooplankton and environmental parameters was conducted along a cross-shelf transect off the coast of Newport, OR, USA (44.65°N) from 1996 to present. Results have demonstrated the feasibility of using copepod community structure as an early indicator of ecosystem response to seasonal and large scale environmental changes in...

Integration of oceanographic information off the Washington and Oregon coasts into west coast groundfish ecology and fisheries management

Creator:

Juan Jorda, Maria Jose

Abstract:

To date, the use of oceanographic data in fisheries management has been limited by the scarcity and the difficulty of accessing complete oceanographic datasets. Consequently, fish stocks are managed with limited knowledge about the habitat where fish live and incomplete understanding of what oceanographic conditions affect their populations. With the...
