<div><p>Using SCUBA techniques allowed us to collect larval krill as close as possible to their in situ condition. Larval krill were collected for time-based experimentation at the dive hole, for shipboard experiments and preserved for later analysis. Samples of the micro-zooplankton community were sampled with suction samplers to gain a better understanding of food available to the larvae relative to their distribution under the ice. In addition, at one of the process stations we were able to deploy drift nets through the dive holes to compare day/night differences in the zooplankton community at depths of 1 m and 10 m below the ice-water interface. <a href="http://www.ccpo.odu.edu/Research/globec/main_cruises02/lmg0205/report_lmg0205.pdf" target="_blank"><em>(from cruise report LMG0205)</em></a></p></div>
station information for larval krill studies, LMGould 0106 and 0205
<div><p>The goal of the larval krill studies was to investigate the physiology and ecology of krill larvae associated with the pack ice and the microbial community on which they feed.</p>
<p>During LMG0106 we occupied two 4-5 day ice stations (Robert and Billy) and sampled several other ice floes opportunistically. We conducted 10 instantaneous growth rate experiments, and 4 whole body clearance time experiments to determine gut passage time (decline in pigment content over time). We also sampled larvae at two additional sites for initial body pigment content (whole body fluorescence), and at 4 sites for condition factor. The under-ice algal community was sampled at one site. Length and stage frequency determinations were also determined.</p>
<p>We occupied three time-series stations of approximately 1 week each, and in addition opportunistically sampled at times when other activities had priority. Our primary goal during the cruise was to occupy three ice camps or process stations with the intent of thoroughly studying the under-ice environment by SCUBA in conjunction with other projects working topside. <a href="http://www.ccpo.odu.edu/Research/globec/main_cruises02/lmg0205/report_lmg0205.pdf" target="_blank"><em>(from cruise report LMG0205)</em></a></p></div>

<div><p>We collected enough krill for 12 Instantaneous Growth Rate (IGR) experiments, 15 collections for whole body (WBF) fluorescence, 11 collections for fecal pellet production (WBC), and 9 collections for condition factor. Measurements of length and stage frequency of the dive and net krill collections were done routinely. <a href="http://www.ccpo.odu.edu/Research/globec/main_cruises02/lmg0205/report_lmg0205.pdf" target="_blank"><em>(from cruise report LMG0205)</em></a></p>
