This hundreth times reduction <strong>of</strong><br />
copepods is related to <strong>the</strong> oxygen<br />
m<strong>in</strong>imum (0.1 ml/l), present <strong>in</strong> this<br />
transect, at around 120 m. OM was<br />
deeper because <strong>of</strong> <strong>the</strong> moderate<br />
2009 El Niño. However Copepods<br />
and Foram<strong>in</strong>ifera and radiolaria<br />
abundances rise moderately aga<strong>in</strong> at<br />
<strong>the</strong> 300-400 and 400-500 m layers.<br />
Euphausiids manta<strong>in</strong>ed <strong>the</strong>ir low<br />
abundance dow to 150 m.
