Multi year ScanFish OPC data Dataset Description: <p>Subsets of these data were published in the papers listed in the "Related Resources" section.</p>
<p>Related dataset:<br />
* Pump mesozooplankton samples:&nbsp;https://www.bco-dmo.org/dataset/746107</p> Methods and Sampling: Methodology:
A CTD and optical plankton counter mounted to a ScanFish platform were towed and undulated behind the vessel.
Sampling and analytical procedures:
The ScanFish was towed at a mean speed of 2.7 m/s with mean vertical descent and ascent rates of 0.3 m/s.
Notes for specific data columns:
Dissolved oxygen concentration (column "oxy"): values corrected vs. CTD rosette casts and Winkler titrations when available.
Sample volume (column "vol"): estimated from OPC mouth opening and changes in lat, lon, and depth
Data column definitions for particle counts and biovolume density include the term "ESD" which stands for "equivalent spherical diameter."
Biovolume densities (data column names beginning with "v_") were calculated using the following formula:
v = sum(4/3*pi*(0.5*ESD*1e-3)^3)/vol
The light attenuance (column "light") has relative units and the OPC unit used starting Sep. 5, 2010 22:30:00 UTC was calibrated differently.

Gulf of Mexico - Deepwater Horizon Oil Spill

Gulf of Mexico - Deepwater Horizon Oil Spill
Grants for Rapid Response Research (RAPID)
The RAPID funding mechanism is used for proposals having a severe urgency with regard to availability of, or access to data, facilities or specialized equipment, including quick-response research on natural or anthropogenic disasters and similar unanticipated events.
GOM - Broader Impacts
The need to understand the impact of this largest oil spill to date on ecosystems and biochemical cycling is self evident. The consequences of the disaster and accompanying clean up measures (e.g. the distribution of dispersants) need to be evaluated to guide further mediating measures and to develop and improve responses to similar disasters in the future. Would it be advantageous if such oil aggregates sink, or should it rather remain suspended? Possibly measures can be developed to enhance sinking or suspension (e.g. addition of ballast minerals) once we understand their current formation and fate. Understanding the particle dynamics following the input of large amounts of oil and dispersants into the water is a prerequisite to develop response strategies for now and in the future.

dataset
Methodology:
A CTD and optical plankton counter mounted to a ScanFish platform were towed and undulated behind the vessel.
Sampling and analytical procedures:
The ScanFish was towed at a mean speed of 2.7 m/s with mean vertical descent and ascent rates of 0.3 m/s.
Notes for specific data columns:
Dissolved oxygen concentration (column "oxy"): values corrected vs. CTD rosette casts and Winkler titrations when available.
Sample volume (column "vol"): estimated from OPC mouth opening and changes in lat, lon, and depth
Data column definitions for particle counts and biovolume density include the term "ESD" which stands for "equivalent spherical diameter."
Biovolume densities (data column names beginning with "v_") were calculated using the following formula:
v = sum(4/3*pi*(0.5*ESD*1e-3)^3)/vol
The light attenuance (column "light") has relative units and the OPC unit used starting Sep. 5, 2010 22:30:00 UTC was calibrated differently.
Specified by the Principal Investigator(s)
Data processing:
Previously processed CTD files (https://www.bco-dmo.org/dataset/3547) and MIDAS files (https://www.bco-dmo.org/dataset/3548) were synchronized and merged with simultaneously collected OPC data. Quality controlled and interpolated MIDAS data were used as the common reference system for longitude, latitude, and time. Since the OPC clock gradually and unpredictably drifted relative to MIDAS time, synchronization was accomplished by measuring and correcting for temporal lag via cross-correlations of moving windows of OPC and CTD pressure sensor time series (with the remaining error generally <0.5 s). Data were then aggregated into 1 s time bins. The standard reference for depth was OPC pressure, adjusted to compensate for non-zero readings on deck of the research vessel over the course of each cruise. The 15 arc second resolution NOAA NCEI coastal relief model for the northern Gulf of Mexico was used as a reference for bathymetry. Data were divided into distinct vertical profiles, and only those profiles were included in the final dataset that either sampled the water column from <3 m below the surface to <3 above the bottom or sampled >30 m of vertical distance, or both. Estimated OPC particle sizes from 256 to 2048 µm equivalent spherical diameter were aggregated into 12 logarithmically spaced size bins (other particle sizes were excluded). For CTD files with both raw and corrected oxygen data, the corrected version was used. All data processing was performed using the R language and environment for statistical computing.
BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date.
* modified parameter names to conform with BCO-DMO naming conventions. Periods in column names changed to underscores.
* added ISO Timestamp column
* rounded decimal places of columns. Number of decimal places provided by data contributor.
* Missing data values are shown as the BCO-DMO missing data identifier "nd" meaning "no data."

Sea-Bird 9 CTD
Sea-Bird 9 CTD
PI Supplied Instrument Name: Sea-Bird 9 CTD Instrument Name: CTD - profiler Instrument Short Name: Instrument Description: The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.
This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934. Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/130/
Focal Technologies Optical Plankton Counter OPC-1T
Focal Technologies Optical Plankton Counter OPC-1T
PI Supplied Instrument Name: Focal Technologies Optical Plankton Counter OPC-1T Instrument Name: Optical Plankton Counter Instrument Short Name:OPC Instrument Description: An OPC provides quantitative measurements of abundance and sizes of mesozooplankton ranging between approximately 0.25 and 14 mm in Equivalent Spherical Diameter (ESD), and has the capability to integrate measurements from other sensors such as a CTD, fluorometer and Global Positioning System (GPS). It can be deployed on a variety of instruments such as SeaSoar, Aries, Scanfish, MOCNESS, a bongo net or simple towing frame. The data from an OPC are typically transmitted to a data acquisition computer through two conducting wires in a towing cable at real time, but it can also be modified to have an internal memory. Large amounts of data are produced. The procedures employed by OPC users vary from; i) estimating integrated biomass by integrating the OPC size distributions, ii) comparing size distributions between OPC and net samples, and iii) simply isolating a size region in the OPC size distribution which correspond solely to specific taxa, eg. Calanus spp..
