MARCO Ocean Maps 4+

Explore over 5,000 interactive maps showing ocean resources and uses in the Mid-Atlantic such as fishing grounds, marine life habitats, reefs and wrecks, and much more!

This app serves as a mobile friendly version of the Mid-Atlantic Ocean Data Portal’s “Marine Planner” GIS web app, developed by the Mid-Atlantic Regional Council on the Ocean (MARCO). Note: Some maps and tools on the MARCO Portal are not available on this app. Visit www.portal.midatlanticocean.org to explore the full data offerings and capabilities of the Portal.

Themes: When users open the app, they are presented with the themes page. From here, they can select a specific theme (data category) to view the layers and sublayers of that theme.

Layers: When a theme is selected, users can view layers and sublayers. The search bar allows filtration of layers. Users can add layers to Active and Favorites tabs, and emojis are used to indicate what layers are currently in those tabs.

Preview: Selecting a layer takes you to a map preview of that layer. Here, users can view informational text on the layer, as well as activate or favorite the layer.

Actives and Favorites: Actives and Favorites tabs display all layers that have been activated or favorited by the user. Active layers are all layers currently being displayed on the main map. Favorites are layers that the user wants to save for easy accessibility. Layers can be deleted, reordered, or activated/favorited respectively from these tabs.

Map: Main map displays all current active layers. Users can toggle layers on and off, view legends for each layer, and view individual layer metadata.

Metadata: Metadata tabs show the specific metadata link for each of the active layers. Users can tap through the metadata by selecting the desired layer at the top of the screen.
