Chesapeake Habitats

The seascapes that harbor fish in the Chesapeake are structured by temperature, salinity, and oxygen.  We have sought to describe the dynamic nature of seascapes by constructing complex multivariable habitat suitability models (Niklitschek and Secor 2009a,b) and relate these to the spatial behaviors of fishes.  NOAA Chesapeake Bay Office is currently supporting development of habitat suitability models for striped bass, modified according to observed preferences of striped bass for certain seascapes.  Support from NOAA Coastal Hypoxia Research Program is allowing us to work with physical and chemical oceanographers to build end-to-end models allowing us to simulate changes to Chesapeake Bay living resource carrying capacity due to scenarios of nutrient inputs and climate change.  Maryland Sea Grant is supporting an effort to develop statistical models that relate living resource changes to coupled human and ecosystem interactions in the Potomac River estuary through an Integrated Ecosystem Assessment. 

  

A moderate-term project supported by the Chesapeake Bay NOAA Office is to evaluate the role of Chesapeake Bay nursery habitats for recent depressed recruitments by Atlantic menhaden.

                                   



Climate Change



The Chesapeake Biological Laboratory supports the oldest climate observing system within the Chesapeake Bay, the CBL research pier.  During the period 1938 to present, temperature has increased c. 2 C.  We have compiled and supplied near daily temperature and salinity records to scientists throughout the nation (Kaushal et al. 2010; Najjar et al. 2010).  Summer and fall juvenile fish collections at the pier, 1999-present, have shown that winter and spring temperature and flow are strong determinants in which fishes are dominant (Wingate et al. 2008).  Thus, coupled environmental-fish community monitoring at CBL provides a unique opportunity to monitor and predict the effects of Chesapeake climate change.   The pier and its observing instrumentation is currently being renovated and enhanced through support by NSF.  http://www.umces.edu/cbl/story/2010/sep/22/historic-cbl-research-pier-to-be-rebuilt
