Integrated Statistics is looking for a Biological Technician to work with the National Oceanic and Atmospheric Administration (NOAA) Northeast Fisheries Science Center (NEFSC) Atlantic Salmon Ecosystems Research Team. The Biological Technician will assist with the analysis of the effects of climate-driven ecosystem change on Atlantic salmon growth and survival at sea, with focus on West Greenland salmon. The Biological Technician will extract growth data from archived scale samples from Atlantic salmon harvested in Greenland from 1969 through to the present.
In the Northwest Atlantic, large-scale climate forcing caused a phase shift in productivity during the 1990s by altering trophic mechanisms that influence growth, survival, productivity and abundance of many species, including Atlantic salmon. The abundance of Atlantic salmon has declined precipitously across its range since that time, despite diverse population structures and management regimes, suggesting that conditions experienced in common marine areas in the Northwest Atlantic may be responsible for current abundance trends. Scales provide a valuable record of growth in Atlantic salmon since they document patterns of growth over the lifetime of a fish. This position will work towards constructing a time series of growth data based on scales from Atlantic salmon harvested and sampled off the coast of West Greenland. The resulting growth data will be analyzed and combined with estimates of marine survival and time series of climatic and oceanographic data to investigate potential hypotheses on the drivers of marine growth and productivity of the species.
The Biological Technician will take responsibility for these tasks:
The successful candidate will possess:
