Fisheries and the Environment (FATE)

Overview

Fisheries And The Environment (FATE) is a NOAA program that supports NOAA’s mission to ensure the sustainable use of US fishery resources under a changing climate. The focus of FATE is on the development and evaluation of leading ecological indicators, their application to practical fishery management problems, and a continuing responsibility to regularly update this information for NMFS stock analysts and the public.

FATE’s role in managing climate-sensitive ecological indicators is to:

  • Develop new climate-sensitive ecological indicators;
  • Maintain time series of these indicators;
  • Examine them for climate trends;
  • Facilitate their incorporation into models used for fisheries and ecosystem management;
  • Continually evaluate this expanding array of ecological and oceanographic indices to be used to improve fishery stock assessments and scientific evaluations needed for resource management.

More information can be found at the FATE website.

ERD scientists are actively involved in FATE research. A principal goal of this work is to quantify long-term variability in key environmental variables and processes in the California Current System. We have studied variability in the magnitude and timing of coastal upwelling, and the impact of variability in water column structure (stratification, thermocline depth) on biological productivity. An ultimate goal is to derive an operational Biologically-Effective Upwelling and Transport Index (BEUTI) that quantifies the effects of wind forcing, water column structure, and nutrient availability.


Offshore


Coastal

Time series of a measure of seasonal water column stratification for an offshore (left) and coastal (right) location in the central CCS. There is significant interannual variability in the amplitude and phase of peak annual stratification over the period 1950-93, as well as different trends between the offshore and coastal locations. The degree and timing of peak stratification can have significant biological consequences, and is thus a good index of physical-biological coupling. From Palacios et al. (2004).
