"NMFS Trawl Survey data was used to fit species distribution models and the
resulting modeled predictions for presence/absence and abundance.
We analyzed the influence of environmental characteristics on the spatial
distribution of our eight focal species using data collected by the Northeast
Fisheries Science Center (NEFSC) spring (March-May), and fall (September-
November) bottom trawl surveys along the Northeast US Shelf (65-75\\u00b0W
longitude, and 35-45\\u00b0N latitude) for the period 1968-2014. Sea surface
temperature, sea bottom temperature, and depth were sampled concurrently with
trawl samples. We used sediment grain size as a measure of substrate type
using existing data layers from the Nature Conservancy. Surveys were trimmed
to strata that were sampled in at least 43 of the 46 years. Data from the fall
and spring surveys 1968-2014 were combined in order to fit species
distribution models (SDMs) using a generalized additive model (GAM) fit
separately for each species. Presence or absence of species x in haul location
i in year y was modeled using a logistic model with a binomial error
distribution and a logit link function. The probability of species occurrence
in each haul was modeled as an additive function of the five environmental
variables and regional species biomass: haul-specific observations of sea
surface temperature, sea bottom temperature, depth, sediment grain size, and
average region-wide biomass (kg/tow) of species x in year y in the season in
which the haul was conducted. Penalized regression splines were fitted using
the \\u201cgam\\u201d function in the mgcv package in R.
In addition to examining changes in overall range size, we also predicted
historical and projected biomass using a delta-lognormal GAM that combines the
predictions of the presence/absence model with that for biomass when present.
Range size and species overlap wer calculated using the R-file
species_overlap_BCO.R available in the \"Supplemental Documents\" section on
this page.";

"Description from NSF award abstract:
Climate change presents a profound challenge to the sustainability of coastal systems. Most research has overlooked the important coupling between human responses to climate effects and the cumulative impacts of these responses on ecosystems. Fisheries are a prime example of this feedback: climate changes cause shifts in species distributions and abundances, and fisheries adapt to these shifts. However, changes in the location and intensity of fishing also have major ecosystem impacts. This project's goal is to understand how climate and fishing interact to affect the long-term sustainability of marine populations and the ecosystem services they support. In addition, the project will explore how to design fisheries management and other institutions that are robust to climate-driven shifts in species distributions. The project focuses on fisheries for summer flounder and hake on the northeast U.S. continental shelf, which target some of the most rapidly shifting species in North America. By focusing on factors affecting the adaptation of fish, fisheries, fishing communities, and management institutions to the impacts of climate change, this project will have direct application to coastal sustainability. The project involves close collaboration with the National Oceanic and Atmospheric Administration, and researchers will conduct regular presentations for and maintain frequent dialogue with the Mid-Atlantic and New England Fisheries Management Councils in charge of the summer flounder and hake fisheries. To enhance undergraduate education, project participants will design a new online laboratory investigation to explore the impacts of climate change on fisheries, complete with visualization tools that allow students to explore inquiry-driven problems and that highlight the benefits of teaching with authentic data. This project is supported as part of the National Science Foundation's Coastal Science, Engineering, and Education for Sustainability program - Coastal SEES.
The project will address three questions:
1) How do the interacting impacts of fishing and climate change affect the persistence, abundance, and distribution of marine fishes?
2) How do fishers and fishing communities adapt to species range shifts and related changes in abundance? and
3) Which institutions create incentives that sustain or maximize the value of natural capital and comprehensive social wealth in the face of rapid climate change?
An interdisciplinary team of scientists will use dynamic range and statistical models with four decades of geo-referenced data on fisheries catch and fish biogeography to determine how fish populations are affected by the cumulative impacts of fishing, climate, and changing species interactions. The group will then use comprehensive information on changes in fisher behavior to understand how fishers respond to changes in species distribution and abundance. Interviews will explore the social, regulatory, and economic factors that shape these strategies. Finally, a bioeconomic model for summer flounder and hake fisheries will examine how spatial distribution of regulatory authority, social feedbacks within human communities, and uncertainty affect society's ability to maintain natural and social capital.";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
