<h1>Experiment on May 06, 2014<a class="headerlink" href="#experiment-on-may-06-2014" title="Permalink to this headline">¶</a></h1>
<p>On May 6, 2014, eight (8) buoys were deployed in the Lower Saint Lawrence Estuary. Each buoy was instrumented with a Global Positioning System (GPS) and a SPOT (<a class="reference external" href="https://www.findmespot.ca/en/">https://www.findmespot.ca/en/</a>). Each buoy was designed with a boyant surface float linked to a drogue via a chain. Three (3) different chain lengths were used in order to observe the effect of the dynamics of the water masses at various depths along the trajectories of the buoys. Each chain length (5, 205 and 750 cm, respectively) was duplicated. Additionally, two buoys were deployed without drogue and allowed to float freely at the water surface.
GPS were programmed to sample every 10 seconds and spots every 5 min.</p>
<p>The buoys were deployed by pairs of matching drogue&#8217;s depth, however due to satellite communication issues, not all GPSs provided data right after deployment. A delay of up to ?? min was observed.</p>
<p>A RDInstrument 300 kHz Acoustic Doppler Current Profiler (ADCP) was deployed for four (4) hours on May 7, 2014 while the buoys were drifting. The ADCP was mounted at the center of a donut-shaped float on a swivel ring to minimize the effects of pitch and roll. The ADCP was programmed to sample the water column using twenty-six (26) 0.5m bins. Vertical velocity profiles were exploited to compare with other estimates of velocity components.</p>
<p>A portable YSI CTD was used to sample vertical profiles of temperature and conductivity at 10 locations in the study area. The data were used to identify different water masses.</p>
<p>In addition, velocity field from MOGSL model output was obtained for comparison purposes.</p>
<p>Tides were obtained from <a class="reference external" href="http://tides.gc.ca/eng/data/table/2014/">http://tides.gc.ca/eng/data/table/2014/</a> at Rimouski.
Hourly wind data were downloaded from <a class="reference external" href="http://climat.meteo.gc.ca/">http://climat.meteo.gc.ca/</a> at station Pointe-au-Père, QC.
Simulated wave data were obtained from the wave model WAVEWATCH III (<a class="reference external" href="http://polar.ncep.noaa.gov/waves/index2.shtml">http://polar.ncep.noaa.gov/waves/index2.shtml</a>) outputs run at UQAR for the area of interest.</p>
