attribute NC_GLOBAL acquisition_description String Physical Influences on Populations in the California Current (Botsford, L.
[Univ. Calif. Davis (UCD)], Hastings, A. M. [UCD], Largier, J. [Scripps
Institute of Oceanography]) We propose to formulate models spanning the
individual level to the metapopulation level for two genera of interest to
GLOBEC in the CCS: ( 1) the two CCS salmon species identified by GLOBEC, coho
salmon (Oncorhynchus kisutch) and chinook salmon (O. tshawytscha) and (2)
Dungeness crab (Cancer magister), a species which covaries with salmon, is a
significant prey of both species, and is subject to similar mesoscale
circulation patterns. The ultimate purpose of these models will be to link the
different scales of variability and levels of ecological organization in the
various retrospective, monitoring and process studies so that the effects of
changes in the physical environment on populations can be projected. Also, we
will answer a number of questions through modeling and analysis of existing
data, that will allow better focus of field studies on critical issues.

While upwelling and the regime shift in the mid-1970s are believed to have
affected survival through this period, results of field studies of the cause
are equivocal. We will develop a model to evaluate the interaction of time of
ocean entry, size at entry, varying growth rate, and size dependent mortality
rate on the fraction surviving this phase, and use it to compare the various
field results in a common context. The results will help to focus field
studies, and the model will provide a framework for evaluation of those
studies. Even though Core Hypothesis III focuses on the juvenile stage, ENSO
events are known to have a dramatic effect on survival of pre-spawning adults.
Because the behavior of random populations of semelparous, anadromous species
is poorly understood, the relative effects of environmental variability on
their persistence and productivity is unknown. We will formulate a population
model to determine which variable life history stage has the greater effect so
that the GLOBEC process studies can focus on the appropriate one. We will
formulate a metapopulation model to evaluate whether covariability between the
environmental influences on different subpopulations affect persistence, and
if it does, whether more productive populations can \"rescue\" extinct less
productive populations?

We will also model and analyze the Dungeness crab population because the
dramatic fluctuations in their abundance along the coast may be caused by the
same environmental factor(s) that cause the salmon populations to vary, and
may also be a cause of that variability through predation. We will apply a new
approach to population analysis that answers the question: which environmental
forcing function can combine with known density-dependent recruitment
mechanisms to produce the observed variability in crab catch? (abstract)

attribute NC_GLOBAL instruments_0_description String The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column and permits scientists observe the physical properties in real time via a conducting cable connecting the CTD to a deck unit and computer on the ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast. This instrument designation is used when specific make and model are not known.

Goal: To understand the effects of climate variability and climate change on the distribution, abundance and production of marine animals (including commercially important living marine resources) in the eastern North Pacific. To embody this understanding in diagnostic and prognostic ecosystem models, capable of capturing the ecosystem response to major climatic fluctuations.
Approach: To study the effects of past and present climate variability on the population ecology and population dynamics of marine biota and living marine resources, and to use this information as a proxy for how the ecosystems of the eastern North Pacific may respond to future global climate change. The strong temporal variability in the physical and biological signals of the NEP will be used to examine the biophysical mechanisms through which zooplankton and salmon populations respond to physical forcing and biological interactions in the coastal regions of the two gyres. Annual and interannual variability will be studied directly through long-term observations and detailed process studies; variability at longer time scales will be examined through retrospective analysis of directly measured and proxy data. Coupled biophysical models of the ecosystems of these regions will be developed and tested using the process studies and data collected from the long-term observation programs, then further tested and improved by hindcasting selected retrospective data series.
