Be-7 from water samples from the Arctic collected on RV Polarstern ARK-XXVI/3. Dataset Description: <p>Be-7 data from water column, meltpond, snow, and ice samples from the Arctic.</p> Methods and Sampling: <p>During the occupation of ice stations, samples from the mixed layer were acquired approximately 150m from the ship to mitigate disruption of surface water properties. A hydrohole was cut through the ice, followed by the lowering of a portable conductivity, temperature, depth probe (CTD) to determine mixed layer depth. A weighted sampling hose was then deployed to the center of the observed mixed layer. Remotely operated vehicle (ROV) observations confirmed that the weighted hose attained accurate deployment-depth measurements from the ice surface. A gasoline generator powered a centrifugal pump which drew water through the sampling hose to the surface where it was passed through iron-oxide impregnated Acrylic fiber filters. A flow meter attached in-line to the filter compartment recorded the amount of seawater passed through each filter. To maximize <sup>7</sup>Be collection, two fibers filtering approximately 600L of seawater apiece were collected from each ice station depth and later combined. The efficiency of the fiber for extraction of Be from seawater was determined by adding stable Be atomic absorption standards to a drum containing seawater, pumping the water through an iron fiber cartridge, and at every 100 L measuring the Be content of the cartridge effluent. Based on several trials, it was found that for sample volumes in the range 400-700L, extraction efficiencies are respectively, 82 ± 3% to 76 ± 2%.</p>
<p>The same filtering apparatus was deployed over the side of the ship to collect <sup>7</sup>Be from waters below the mixed layer, and from open-ocean mixed layers when not in the ice. At each ice station, a submersible in-line pump was deployed over the side of the ship to a depth of 40m for sampling below the mixed layer. This was used to fill two 1000L holding tanks, from which up to 700L of seawater was passed through one fiber filter each as was done with the mixed-layer samples. For open-water sampling, the ship’s seawater system drew water from the mixed layer at a depth of 8m and filled two holding tanks for immediate filtration. All fibers were returned to the lab where they were dried, ashed, and placed in a Marinelli beaker, which in turn was placed over a low background germanium gamma detector. <sup>7</sup>Be has a readily identifiable peak at 478keV. The detector is calibrated for these samples by adding a commercially prepared mixed solution of known gamma activities to an ashed fiber and counting it in the Marinelli geometry.</p>
<p>Melt pond water, ice, and snow samples were collected as well. Melt pond samples consisted of 50L of water from undisturbed ponds which were typically 50cm deep. Ice core samples were taken from the ice surface to seawater, producing a core 14cm in diameter and generally 2m in depth. When snow was present, it was removed from the surface of the ice prior to ice coring. All samples were melted and received 5mL of concentrated HCl, 5mL of FeCl in solution, and 0.5mL of a stable Be tracer. After 12 hours of equilibration, a concentrated NaOH solution was slowly added to coprecipitate the <sup>7</sup>Be with Fe(OH)<sub>3.</sub> The precipitate was returned to the lab where it was dried, placed in Petrie dishes, and counted by gamma spectroscopy calibrated for this geometry.&nbsp; The precipitate was redissolved in dilute HCl, and analyzed for stable Be by atomic absorption to calculate recovery yields.</p>

Sample Analysis to Test a Novel Method of Determining Atmospheric Deposition of Trace Elements to the Ocean/Ice System of the Arctic

Sample Analysis to Test a Novel Method of Determining Atmospheric Deposition of Trace Elements to the Ocean/Ice System of the Arctic
<p><em>Description from the NSF award abstract:</em><br />
The investigators propose to use the naturally occurring isotope beryllium-7, which is produced in the atmosphere by cosmic rays and has a 53.3-day half-life, as a tracer for estimating the atmospheric fluxes of a variety of trace elements to the surface of the Arctic Ocean. They have collected samples of snow, sea ice, surface waters, and atmospheric aerosols through an international collaboration concurrent with the preparation of this proposal. This project provides funding for the analysis of Be-7 and for trace elements including aluminum, manganese, iron, cupper, zinc, cadmium, and lead. The atmospheric input of numerous chemical species into the global ocean has been shown to equal or exceed that from river sources. In the Arctic, several contaminant elements in particular are dominated by atmospheric sources, with implications for the Arctic ecosystem and human health. The project will investigate several elements of interest to the international GEOTRACES program, which is currently formulating plans for coordinated Arctic work. The project will support a Ph.D. student who will incorporate these results into his dissertation.</p>

CTD
CTD
PI Supplied Instrument Name: CTD PI Supplied Instrument Description:During the occupation of ice stations, a hydrohole was cut through the ice, followed by the lowering of a portable conductivity, temperature, depth probe (CTD) to determine mixed layer depth. 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/
Ice Corer
Ice Corer
PI Supplied Instrument Name: Ice Corer PI Supplied Instrument Description:Ice core samples were taken from the ice surface to seawater, producing a core 14cm in diameter and generally 2m in depth. Instrument Name: Ice Corer Instrument Short Name:Ice Corer Instrument Description: An ice corer is used to drill into deep ice and remove long cylinders of ice from which information about the past and present can be inferred. Polar ice cores contain a record of the past atmosphere - temperature, precipitation, gas content, chemical composition, and other properties. This can reveal a broad spectrum of information on past environmental, and particularly climatic, changes. They can also be used to study bacteria and chlorophyll production in the waters from which the ice core was extracted.

PI Supplied Instrument Name: ROV PI Supplied Instrument Description:A hydrohole was cut through the ice, followed by the lowering of a portable conductivity, temperature, depth probe (CTD) to determine mixed layer depth. A weighted sampling hose was then deployed to the center of the observed mixed layer. Remotely operated vehicle (ROV) observations confirmed that the weighted hose attained accurate deployment-depth measurements from the ice surface. Instrument Name: Remotely Operated Vehicle Instrument Short Name:ROV Instrument Description: Remotely operated underwater vehicles (ROVs) are unoccupied, highly maneuverable underwater robots operated by a person aboard a surface vessel. They are linked to the ship by a group of cables that carry electrical signals back and forth between the operator and the vehicle. Most are equipped with at least a video camera and lights. Additional equipment is commonly added to expand the vehicle’s capabilities. These may include a still camera, a manipulator or cutting arm, water samplers, and instruments that measure water clarity, light penetration, and temperature.
