Advection: supply/loss to GOM
Background
• Are GB copepods endogenous to GOM or exogenous (SS,
Slope water)?
• Deep-water circulation affects supply/loss to basins:
• retaining and/or concentrating animals in the basin gyres
• advectively connecting the basin populations residing above the
shallowest closed isobath
• advecting Slope Water animals into the GOM through the NEC
• Exchange of slope and basin copepod populations
profoundly affected by strongly interannually varying
winds
• Turnover of diapausing populations in late summer/fall
