Below are the first 10 and last 10 pages of uncorrected machine-read text (when available) of this chapter, followed by the top 30 algorithmically extracted key phrases from the chapter as a whole.
Intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text on the opening pages of each chapter. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

Do not use for reproduction, copying, pasting, or reading; exclusively for search engines.

APPENDIX B NPRB 2002-2003 Research Priorities 2002 Marine ecosystem form and function: Factors affecting marine produc- tivity, including nutrient transport and availability, water column stability and the role of sea ice; influence of climate variability on physical, chemical, and biological processes; unusual occurrences of specific organisms such as the coccolithophorid blooms; development of ecosystems models that will aid resource managers Endangered and stressed species: Factors affecting survival of stressed and endangered species, particularly marine mammals and seabirds; responses to ocean climate trends and prey availability Fish habitat: Mapping of bottom habitats to document presence of corals or other sensitive substrates; studies of factors affecting habitat including physical forcing, variations in energy flux, and overwintering conditions; impacts of fisheries and other human influence on benthic habitat and its capacity to support communities of organisms Fishing capacity reduction: Studies of ways to reduce fishing capacity, including rights-based systems Bycatch: Studies that assess impacts of, or lead to reductions in, bycatch of juvenile fish or non-target species (including salmon), including gear designs to improve selectivity 98
