| Title: |
Moored sediment trap observations collected from fixed moorings in the Great Lakes region and Yellowstone Lake, Wyoming from 1977-04-28 to 2005-03-15 (NCEI Accession 0266598) |
| Abstract: |
This collection contains sediment trap observations from 2,743 samples in the Great Lakes region from 1977-2005 and Yellowstone Lake, Wyoming from 1995-1996. We included measurements of trap material sample weight, mass flux and constituents (total and organic carbon and organic nitrogen). Details about the sediment trap design and deployment are described in Muzzi and Eadie (2002) and details about the trap sampling methods are described in Eadie et al. (2000). Processing procedures for preparing sediments and running constituents analyses provided in the Supplemental Information. File formats included in this data package are csv. |

Total Carbon, Organic Carbon and Organic Nitrogen Great Lakes Trap Sample Processing Field Collection and Storage Trap bottles were capped on the ship deck, kept in coolers, transported back to the lab in coolers and stored upright under refrigeration. Samples were left to settle in the refrigerator until overlying water in the sample bottle was clear of suspended particles. Size Fractionation Approximately 30 ml of overlying water in a trap bottle was decanted into a beaker (to be used as a rinse). The remaining sample was shaken, sonified, and immediately poured through a 355 micron screen into a clean beaker. To ensure quantitative transfer of material from the trap bottle, it was rinsed with the overlying water previously set aside (see above). If there was still residual material in the trap bottle a DDW rinse was used. (In these cases we would try to minimize the use of DDW). The >355 micron fraction collected on the screen was back-rinsed off the screen and collected onto tared Whatman GF/F filters 4.7cm using a vacuum filter flask. These filters are dried at 70°C and weighed to determine >355 micron size fraction. The |
