The data are therefore not directly comparable between these surveys. The specificities of the missions onboard the MV Lady Hammond are described below. Objectives: Assess groundfish populations abundance and condition Assess environmental conditions Conduct a biodiversity inventory of benthic and demersal megafauna Monitor the pelagic ecosystem Collect samples for various research projects Survey description The survey covers the northern Gulf of St. Lawrence, that is the divisions 4R, 4S and the northern part of division 4T of the Northwest Atlantic Fisheries Organization (NAFO).
