Marine Microplastics: Help

The Microplastics Map Viewer enables users to view, filter, and download marine microplastics related data sets from the archive holdings of the National Centers for Environmental Information (NCEI). Data are viewed, filtered, and downloaded using the left-hand side panel. See the below sections for more detail on using the left-hand side panel. For questions about how to use the Microplastics map viewer, please contact the NCEI user service ncei.info@noaa.gov.

Datasets

There are three datasets: AdventureScientist, SEA, and GEOMAR. Click on the    symbol next to each layer in the Layers section to access each dataset's metadata landing page from within NCEI's archives.
Note: SEA is archived as two separate datasets.

Filtering

Data can be filtered spatially and temporally using a combination of the draw tool and date range widget. To filter the data by a geographic bounding box, first click the    icon in the top-left corner of the map to activate the draw tool. Then, click and drag to draw a rectangle representing a geographic bounding box over the map. The Layers section of the left-side panel automatically updates to show which layers are available and how many features are in each layer with the spatial filter applied. Next, in the Date Range section, use the dropdown to choose particular calendar dates or enter dates in YYYY-MM-DD format into the Start date and End date boxes. The Layers section updates again as dates are entered to display the features available for viewing or downloading within the specified temporal range. Click the Reset Filters button to remove all applied filters from the data.

Viewing

After desired filters are applied, click the Draw Data button to draw the data on the map. Click on a data point to view that feature's attribute data in a pop-up. Click the Clear Data button to remove the data from the map.

Downloading

At any point, click the download icon next to a layer's feature count in the Layers section to download those features to CSV format.

Search Example

Imagine you are looking for data off the coast of Jamaica that was captured during the 1990s.

Here is how you can do the search:

  1. On the map: Move the mouse cursor over top of the Caribbean Sea. Then, use the mouse scroll wheel or zoom icons in the top right corner of the map to zoom in. Click and drag with the mouse to pan the map to center it over Jamaica. Click the    icon to activate the draw tool. Then, click, hold and drag over the map to draw a rectangle around Jamaica.
  2. In the Date Range section: enter “1990-01-01” in the Start date box and "1999-12-31" in the End date box.
  3. After applying map and/or date filters, the Layers section automatically updates to show which layers are available and how many features are in each layer with the selected filters applied.
  4. Next, click the "Draw Data" button to draw the data on the map.
  5. Click on data points on the map to see each feature's attribute data.
  6. To download these features to CSV format, click the download icon in the Layers section next to the layer you want to download.
