Welcome to the STAC

The Science and Technical Advisory Committee (STAC) is a diverse body of scientists and resource managers who lend their technical expertise to enhance the health of the Delaware Estuary and its resources. The STAC work collaboratively to provide expert advice and peer review for scientific and technical matters related to the National Estuary Program’s activities and goals. The STAC is responsible for identifying and prioritizing science and technical needs, and it assists in PDE’s efforts to raise awareness and funding resources. STAC members assist PDE by serving on other technical committees, and representing the needs of the Delaware Estuary. In addition to general quarterly meetings, STAC sub-committees get their hands dirty by meeting more frequently to work on pressing issues.
