Upper ocean spatial variations were strongest for
composite nutrient
|
|
|
profiles; deeper waters were relatively invariant
|
|
|
| • |
Offshore-onshore variations in mixed layer nutrients
were pronounced,
|
|
|
especially for ammonia, with Marguerite Bay
providing a significant
|
|
|
endmember.
|
|
|
| • |
Nearshore mixed-layer ammonia maxima were co-located
with a coastal
|
|
|
current, at least in year 1 of GLOBEC
|
|
|
| • |
Mixed-layer nitrate, phosphate, and silica
concentrations appeared in
|
|
|
steady-state, while ammonia concentrations and
standing stocks showed
|
|
|
strong, erratic seasonal and year-to-year declines.
|
|
|
| • |
An inverse -3 mol:mol relationship between nitrate
and ammonia existed
|
|
throughout all GLOBEC cruises and for an autumn
JGOFS Ross Sea
|
|
|
cruise.

Silica was an excellent tracer of upwelling and
horizontal injection of
|
|
|
offshore waters onto the West Antarctic Shelf
