Underway temperature, salinity, density, fluorometry, PAR, oxygen, etc. Dataset Description: <p>Underway temperature, salinity, density, fluorometry, PAR, oxygen, roll, pitch, altitude, distance, date, position, depth, water depth and turbidity measurements collected during the VPR survey by Scientific Computer System (SCS) software developed at NOAA for the NOAA fleet and the instrumentation on the VPR instrument. SCS data are generally only collected while the ship is underway. A variety of sensors can be connected to the system. Please see the list of instruments for specific information.</p> Methods and Sampling: <p>The SCS data files logging the raw data are set to break once a day at GMT midnight to make acquisition, plotting, processing and transfer easier.</p>
<p>The following information is quoted from SOI's &quot;Guide to SCS Data Sensors and Formats SCS v 4.6.0&quot;, by MT Colleen Peters, 2013. There is additional information available in this document that may be relevant to users of these data.</p>

The Seapath 320 position and attitude data are utilized by the multibeam sonars. The CNAV display is located in the rack room.&nbsp;The antenna is located on the starboard side of upper main mast.

<div>&nbsp;</div>
</div>
</div>
<div>
<div><b>Vaisala WXT520:&nbsp;</b>The <span>weather data comes from a sensor mounted on the upper level of the main mast.&nbsp;The Vaisala WXT520 collects wind direction and speed as well as air temperature, relative humidity and pressure.&nbsp;The sensor is directly connected to the bridge Helideck Monitoring System (HMS).&nbsp;The data are then output from the HMS 100 to the network and brought into SCS. </span></div>
</div>

<div><b>Lambrecht QUATRO IND-H&rsquo;:</b> The second sensor, the Lambrecht QUATRO IND-H&rsquo; measures wind speed and direction, as well as pressure, air temperature and relative humidity. The met data is only connected to the bridge display on the navigation station. The wind data are then output to the bridge&rsquo;s Raytheon navigation system and sent through the network in the <b>BridgeData</b> string. This sensor is for navigation only, and does not get calibrated.</div>
<div>&nbsp;</div>
<div><b>Biospherical Surface Photosynthetically Active Radiation (PAR) Sensor : </b>A PAR sensor with a <u>spherical receiver</u> that is equally sensitive to photons from all direction measures&nbsp;Quantum Scalar Irradiance (QSI). An alternative term for this quantity is &quot;Photosynthetic Photon Flux Fluence Rate&quot; (PPFFR). QSI or PPFFR are defined as the integral photon flux of photons in the 400&ndash;700 nm wavelength interval&nbsp;at a point in space from all directions around the point.</div>
</div>
<div>&nbsp;
<div><b><i>S</i></b><b><i>cientific <span>Seawater System</span></i></b><b>:&nbsp;</b>Th<span>is system was designed to run a continuous flow of seawater through several instruments to measure the properties of the surface water. The intake for this system in is the bow, and the equipment (pump, plumbing and external temperature probe) are all located forward of the bow-thruster room. </span></div>
<div>&nbsp;</div>
<div>Gener<span>ally, all sensors are turned on as soon as the ship is in clear water when leaving port and run for the duration of the cruise. Running the system in an environment prone to chemicals from ships and land facilities can damage the sensitive sensors. Sometimes, when the ship is in rough weather, the seawater system may catch an air bubble, which can disrupt the data, or require the system to be shut down temporarily. These occasions can be easy to identify by plotting the two temperature measurements&mdash;if the TSG temperature is high (like 5&deg;C difference) then there is likely no flow in the system, which allows the TSG temperature to increase to room temperature, while the remote probe will stay at ocean temperature. This will vary with the local ocean temperatures.</span></div>
</div>
<div>&nbsp;</div>
<div>
<div><b><i>SB</i></b><b><i>E<span> 38 Remote Temperature Probe</span></i></b>:&nbsp;The <span>&lsquo;external&rsquo; or remote probe, SBE 38 measures temperature as close to the system&rsquo;s intake as possible. When we send &lsquo;sea surface temperature&rsquo; data, we primarily use this sensor. This temperature is used to calculate sound velocity with the TSG.</span></div>

<div><b>Seabird 9/11 plus </b><b>C</b><b>onductivity Tem<span>perature and Depth (CTD):&nbsp;</span></b>CT<span>Ds are standard oceanographic systems on most ocean-going research vessels. This system provides a profile of the water column, measuring the chemical and physical properties of the water.</span></div>
<div>&nbsp;</div>
<div>The CTD data is logged using the Seabird Seasave software, and also logged in SCS as a backup. It is helpful to view the CTD depth on a real time plot with winch wire out. It is also useful for comparing sea-surface temperature between the SBE 38and SBE 9plus. The CTD is a 6800m rated sensor with dual temperature and conductivity sensors. It can accommodate up to 8 auxiliary sensors. We currently have 2 SBE 43 dissolved oxygen, a WetLabs ECO FLNTU fluorometer/turbidity sensor and a C-Star Transmissometer. Due to the nature of CTD casts, the auxiliary instruments can change frequently within a cruise or between cruises, so the data are not accommodated in SCS. It would require frequent reprogramming, which would interrupt the bulk of the data being logged on SCS. The primary sensors are therefore the only ones logged by SCS. These include pressure, depth, conductivity, temperature, salinity and sound velocity.</div>
<div>&nbsp;</div>
<div>The CTD frame and SBE 32 carousel can accommodate up to 24 12L OTE Niskin water sampling bottles.</div>

<div>&nbsp;</div>
<div><span>
<div><b><u>Scientific Echo sounders</u></b></div>
<div>All of the following echo sounders are from Kongsberg Maritime. In normal mapping operations, the data from each of the sounders are recorded on the local acquisition machines in the Kongsberg file formats for more in-depth processing. They are recorded on SCS for use with displays, quality assurance and data transfers to the SOI website Falkor Status page. If you want to process any of these data for acoustic surveys, you will need the files in the native formats.</div>

<div><b>EM302 Deep water multibeam sonar: </b>The EM302 is used for seafloor bathymetry, seafloor backscatter and water column backscatter. This sonar&rsquo;s optimal depth is 1000-6000m, but it can log data from 10-8000m.</div>
<div><b>&nbsp;</b></div>
<div><b>EM710 Shallow water multibeam sonar: </b>The EM710 is used for seafloor bathymetry, seafloor backscatter and water column backscatter. This sonar has higher resolution in more shallow depths, and its operating range is up to 2000m, but it tends to stop collecting useful data by 1500m.</div>
<div><b>&nbsp;</b></div>
<div><b>EK60 Split-beam fisheries sonar: </b>The EK60 sonar is generally used for studying the plankton or fish in the water column. There are the following frequencies: 12kHz, 38kHz, 70kHz, 120kHz, 200kHz and 710kHz.</div>
<div><b>&nbsp;</b></div>
<div><b>EA600 Single-beam hydrographic sonar: </b>The EA600 is not frequently used for logging data. It&rsquo;s primary function is to find the bottom quickly before an ROV dive or CTD cast or to compare to another sonar. There are the following frequencies: 12kHz, 38kHz, 120kHz and 200kHz. The 12kHz EA600 is one of two transducers that will collect data to the bottom of the Marianas Trench, roughly 11,000m in depth.</div>

RAPID: High-resolution sampling of plankton taxa, marine snow, and environmental variables across the north Atlantic subpolar gyre

RAPID: High-resolution sampling of plankton taxa, marine snow, and environmental variables across the north Atlantic subpolar gyre
<p>This project used the opportunity of a ship crossing the North Atlantic at high latitude to conduct a high-resolution sampling transect of mesozooplankton, marine "snow" (biogenic aggregates), and environmental variables from the northwestern UK shelf to southern Greenland via a route south of Iceland, thence south across the Labrador Sea and the Grand Banks to the slope water south of Nova Scotia, Canada. Sampling was done with the fast-tow Video Plankton Recorder II (VPRII). The VPR enables non-destructive sampling of fragile plankton in situ, and through rapid towyo deployments (continuous raising and lowering while under way), it provides high vertical (top 150 m) and horizontal (1km towyo spacing) resolution of robust as well as fragile plankton and aggregates and numerous environmental variables. The VPRII had been deployed in several locations around the world, but, until this cruise, there was no comparable data set for the far North Atlantic, an area of intense ecological interest. This opportunity arose from the transatlantic maiden voyage of the Schmidt Ocean Institute's (SOI) new research vessel, R/V <i>Falkor</i>, from the UK to the Woods Hole Oceanographic Institution from July 2-28, 2012. SOI funded ship costs for the transit, making the underway VPR survey a cost-effective way to sample. This project collected a major data set that can be quickly processed (acoustic, hydrographic, automated image analysis) and will be available to the community soon. Two Ph.D. students participated in the cruise, adding to their training in oceanography and high latitude marine science. </p>
<p>This project was funded by the National Science Foundation. In addition, the VPRII upgrade was supported by the Marine Science and Technology Foundation (WHOI #17073) and the Schmidt Ocean Institute provided the ship itself, the R/V Falkor.</p>

These include pressure, depth, conductivity, temperature, salinity and sound velocity.</div>

<div>The CTD frame and SBE 32 carousel can accommodate up to 24 12L OTE Niskin water sampling bottles.</div>

<div><b>Kongsberg Maritime Skipper DL850 Dual Axis Doppl<span>er Speed Log: </span></b>Prov<span>ides forward/aft (+/-) and port/starboard (+/-) ship speed measurements, both over ground and through water.&nbsp;The speed range is from 0-40 knots on both axis. The echo sounder has a max range of 100m. </span></div>

<div><b><u>Scientific Echo sounders</u></b></div>
<div>All of the following echo sounders are from Kongsberg Maritime. In normal mapping operations, the data from each of the sounders are recorded on the local acquisition machines in the Kongsberg file formats for more in-depth processing. They are recorded on SCS for use with displays, quality assurance and data transfers to the SOI website Falkor Status page. If you want to process any of these data for acoustic surveys, you will need the files in the native formats.</div>

<div><b>EM302 Deep water multibeam sonar: </b>The EM302 is used for seafloor bathymetry, seafloor backscatter and water column backscatter. This sonar&rsquo;s optimal depth is 1000-6000m, but it can log data from 10-8000m.</div>
<div><b>&nbsp;</b></div>
<div><b>EM710 Shallow water multibeam sonar: </b>The EM710 is used for seafloor bathymetry, seafloor backscatter and water column backscatter. This sonar has higher resolution in more shallow depths, and its operating range is up to 2000m, but it tends to stop collecting useful data by 1500m.</div>
<div><b>&nbsp;</b></div>
<div><b>EK60 Split-beam fisheries sonar: </b>The EK60 sonar is generally used for studying the plankton or fish in the water column. There are the following frequencies: 12kHz, 38kHz, 70kHz, 120kHz, 200kHz and 710kHz.</div>
<div><b>&nbsp;</b></div>
<div><b>EA600 Single-beam hydrographic sonar: </b>The EA600 is not frequently used for logging data. It&rsquo;s primary function is to find the bottom quickly before an ROV dive or CTD cast or to compare to another sonar. There are the following frequencies: 12kHz, 38kHz, 120kHz and 200kHz. The 12kHz EA600 is one of two transducers that will collect data to the bottom of the Marianas Trench, roughly 11,000m in depth.</div>
