Zooplankton razing Rates - Experiments conducted aboard the Umitaka-Maru, 2015
No problems were encountered in the collection of these data. The dataset was developed during a cruise on the Umitaka-maru along the 110 E meridian from Fremantle to the ice edge. At five stations, zooplankton were collected and specimens selected for grazing experiments. They were added to 2L bott...
