<div><p>The HROV Nereus was used to conduct exploration and characterization (including downloading video seafloor transects) of the Kermadec Trench region in May 2014. Geo-referenced vehicle navigation was conducted using the R/V Thompson’s GPS launch position of the vehicle, the estimated initial on bottom position of the vehicle, the course over ground (determined by the Gyro heading, Doppler Velocity Profiler, and thruster speed).</p>
<p>Navigation processing was conducted Matlab (2011 Release; MathWorks, Inc.) and Microsoft Excel for Mac 14.7.3.</p>

HADES-K - Nereus bottom navigation
<div><p>This dataset includes HROV/Nereus dive bottom navigation in the Kermadec Trench calculated from course, speed and distance from origin, April/May 2014. The dives were in the Southwest Pacific, 4000 to ~10,000m from the RV/ Thomas G. Thompson during cruise TN309 (HADES-K), April - May 2014.</p></div>
HADES-K Nereus dives - bottom navigation
<div><p><strong>BCO-DMO Processing Notes:</strong><br />
- added conventional header with dataset name, PI name, version date<br />
- modified parameter names to conform with BCO-DMO naming conventions<br />
- re-formatted date from m/d/yyyy to yyyy-mm-dd<br />
- concatenated all the dive data into a single file<br />
- added column for temp and altitude if not present in dive file<br />
- reduced lat and lon digits from 7 to 5 to right of the decimal<br />
- added date_start, obtained from PI submission, differs somewhat from HadesK_deploylog dataset</p></div>
