Help on the Results MapX
This window can be dragged by its header, and can be resized from the bottom right corner.
Clicking the Layers button - the blue square in the top left of the Results Map - will display a list of map layers you can add or remove
from the currently displayed map view.
The Results Map and the Results Table
- The Results Map displays the centroids of the geographic bounds of all the results returned by the search.
- Results that are displayed in the current map view will be highlighted in blue and brought to the top of the Results Table.
- As the map is panned or zoomed, the highlighted rows in the table will update.
- If you click on a centroid on the map, it will turn yellow and display a popup with details for that project/dataset - including a link to the landing page. The bounds for the project(s)/dataset(s) selected will be displayed in red. The selected result(s) will be highlighted in red and brought to the top of the table.
- The default table sorting order is: Selected, Visible, Date (descending), but this can be changed by clicking on column headers in the table.
- Selecting Show on Map for an individual row will both display the geographic bounds for that result on a mini map, and also display the bounds and highlight the centroid on the Results Map.
- Clicking the 'Show boundaries' checkbox at the top of the Results Map will display all the bounds for the filtered results.

Collaborative Research: Sea ice as a driver of Antarctic benthic macroalgal community composition and nearshore trophic connectivity |
The purpose of this dataset was to determine the importance of macroalgal primary producers to the coastal invertebrate food webs along a gradient of sites with increasing mean annual sea ice cover. This dataset contains the carbon and nitrogen stable isotope values, in addition to carbon and nitrogen content, of various coastal primary producers and invertebrate consumers from 15 stations along the Antarctic Peninsula from 64 to 69 degree latitude south collected in 2019. Primary producers included multiple species of macroalgae, particulate organic matter (POM) as a proxy of phytoplankton production, and benthic diatoms (where they occurred). Consumers included various benthic invertebrates of different feeding types, from suspension feeders (like sponges and ascidians) to predators/omnivores (like sea stars). | ["POLYGON((-68 -64.5,-67.5 -64.5,-67 -64.5,-66.5 -64.5,-66 -64.5,-65.5 -64.5,-65 -64.5,-64.5 -64.5,-64 -64.5,-63.5 -64.5,-63 -64.5,-63 -64.95,-63 -65.4,-63 -65.85,-63 -66.3,-63 -66.75,-63 -67.2,-63 -67.65,-63 -68.1,-63 -68.55,-63 -69,-63.5 -69,-64 -69,-64.5 -69,-65 -69,-65.5 -69,-66 -69,-66.5 -69,-67 -69,-67.5 -69,-68 -69,-68 -68.55,-68 -68.1,-68 -67.65,-68 -67.2,-68 -66.75,-68 -66.3,-68 -65.85,-68 -65.4,-68 -64.95,-68 -64.5))"] | ["POINT(-65.5 -66.75)"] | false | false |

The dataset consists of the daily (or weekly in the case of NIC) timeseries for the available period of record beginning in 1979 for the Sea Ice Index and extending until April 1, 2019. The sea ice concentrations were extracted from the nearest corresponding pixels from the fifteen study sites associated with visited by projects ANT-1744550, -1744570, -1744584, and -1744602 during ARSV Laurence M. Gould cruise LMG 19-04 in April and May 2019. In addition to the original time series, five-year annual means starting on April 1st are computed for the Sea Ice Index, AMSR2 and NIC datasets all of which covered the 2014-2019 period.

Collaborative Research: Sea ice as a driver of Antarctic benthic macroalgal community composition and nearshore trophic connectivity |
This csv dataset contains diffuse attenuation coefficients (units: m-1) from the Visible Infrared Imaging Radiometer Suite (VIIRS) Kd(490) product. The values are from the nearest corresponding pixels from the fifteen study sites associated with visited by projects ANT-1744550, -1744570, -1744584, and -1744602 during ARSV Laurence M. Gould cruise LMG 19-04 in April and May 2019. These attenuation coefficients were generated by the NOAA CoastWatch/OceanWatch program. They are remote sensing estimates of diffuse attenuation coefficients at a 490 nm wavelength in for approximately 4x4 km cells using the algorithm described in (Wang et al., 2017). The dataset includes January-February-March (JFM), October-November-December (OND) as well as October to March averages for each site. OND averages are not available for all sites and therefore are not included in the October-March averages. An indication of the distance from the site to the nearest pixel with a Kd(490) observation is noted. Wang, M., X. Liu, L. Jiang, and S. Son. 2017.

Collaborative Research: Sea ice as a driver of Antarctic benthic macroalgal community composition and nearshore trophic connectivity |
This csv dataset includes the fetch distances for the 15 study sites visited by projects ANT-1744550, -1744570, -1744584, and -1744602 during ARSV Laurence M. Gould cruise LMG 19-04 in April and May 2019. The fetch distances were computed for each of the following eight cardinal directions (0°,45°,90°,135°,180°,225°,270°,315°). The fetches are all reported in meters (m). Fetch was determined by computing the distance along each of the eight directions to the nearest shoreline based on a 100 m resolution land/water grid. The grid was constructed using a vector-to-raster conversion of the Scientific Council of Antarctic Research (SCAR) Antarctic Digital Database’s High resolution vector polylines of the Antarctic coastline. The fetch computations utilized an ArcGIS toolbox based on code by Finlayson (2006) that computes fetch using the recommended procedures from the US Army Corp of Engineers Shore Protection Manual (USACE, 1984).
