Georges Bank Fish Larvae, Growth Rates, Protein Content and Otolith Data Collected from BONGO Nets, 1995-1999.
<div><p>Principle objectives of the US GLOBEC Georges Bank Program were to study the composition of the larval fish community on Georges Bank, to define larval fish distribution across the Bank and within the water column, to determine those factors which influence their vertical distribution, and to determine bank-wide versus "Patch-Study" mortality and growth rates. Emphasis is on Atlantic cod <span class="st"> (Gadus morhua) </span>and haddock <span class="st">(Melanogrammus aeglefinus)</span> larvae along with their predators and prey. This study also includes larval distribution and abudance, analysis of feeding habits, and age and growth determination. These objectives were implemented through the use of bongo nets and MOCNESS tows to make the animal collections.</p></div>

<div><p><b>BCO-DMO Processing Notes:</b></p>
<div>- Original data file was edited in excel to add BCO-DMO convention header line, cruise and PI comment lines.
<p>- Because the original file: “Buckley data for Georges Back GLOBEC website 8-6-2012.xls” contained both Bongo and MOCNESS data, it was subsequently split into three separate data files based on gear and cruise type. These datasets are served separately:</p></div>
<ul><li>fishlarvae_M1 contains data from MOCNESS tows</li>
<li>fishlarvae_Bon_pro contains Bongo data from process cruises only</li>
<li>fishlarvae_Bon_bss contains Bongo data from broadscale cruises only</li>
</ul><p>Additional edits to this dataset, fishlarvae_Bon_bss:</p>
<p>-Stations with redundant entries were compared to the eventlog for the cruise and, where needed, lat/lon values were edited to a consistent precision for all positions taken at the same date/time.</p>
<p>- Two stations (6 and 36.5) in deployment EN282 in fishlarvae_Bon_bss contained identical information for station lat/lon, time, depth, avg sal, etc. but different day and yrday. When validated against other files' station information at the same location, time, etc. the day and yrday were corrected (fishlarvaeB and the eventlog for EN282 were used to validate):<br />
Station 6: day 12, yrday0 102 was edited day 11, yrday0 101<br />
Station 36.5: day 19, yrday0 109 was edited to day 18, yrday0 108</p>
<p>- Edited precision for sal_avg, temp_avg, sigma_t_avg to three decimals.</p>
<p>- Edited values of 99 for sal_avg, temp_avg, sigma_t_avg to "nd".</p>
<p>- Parameter names were edited to adhere to BCO-DMO and GLOBEC convention, of particular note:</p>
<ul><li>Tow was edited at the request of the PI. Station and not station_std was used due to the fact that some stations correspond to GLOBEC GB standard station numbers. However, some do not. Within the GLOBEC context, standard station numbers were reserved for specific stations with exact locations where core survey measurements were carried out (please refer to <a href="http://globec.whoi.edu/globec-dir/protocol-bs-stations-1996.html">http://globec.whoi.edu/globec-dir/protocol-bs-stations-1996.html</a>). The DMO prefers to reserve the 'standard' label for the above defined stations.</li>
</ul><div>
<ul><li>EDST was edited to time_local</li>
<li>Species was edited to common_name because sometimes the animal was identified only to family or other taxonomic level.</li>
<li>Cruisetype was edited to brief_desc</li>
</ul></div>
