BOEM’s Marine Minerals Information System (MMIS) Data Services are Relocating

Release Date

Dear Stakeholder,

BOEM’s Marine Minerals Information System (MMIS) data services are relocating on July 9, 2024. Please refer to the table below for the updated locations of BOEM’s MMIS data services.

MMIS provides an Enterprise Geospatial Information System (GIS) environment to support BOEM’s marine minerals leasing and environmental reviews. MMIS is a collection of over 30 years of geophysical (e.g., shallow seismic, bathymetry, and sidescan sonar) and geotechnical (e.g., vibracore and sediment grab locations and associated laboratory analyses) derived data and information products. These datasets are critical to supporting Outer Continental Shelf (OCS) beach nourishment and coastal storm risk management projects and helping to mitigate OCS space-use conflicts.

Migrating MMIS to GeoSEAS, a cloud platform, will allow BOEM to leverage the power and additional features of Esri’s ArcGIS Online (AGOL). As a result, each service can now be accessed as an AGOL item or through a REST endpoint as users are accustomed to doing within ArcPro. The details of some services have changed, and BOEM has added new services for easy access to commonly-used layers.  

BOEM’s new MMIS Viewer Application is planned for a late summer launch. BOEM will issue a Note to Stakeholders in advance of the launch.

Please see the table below for a side-by-side comparison of BOEM’s existing and new public services, including access information.

More about MMIS:

Established in 2019, the MMIS provides a means for BOEM to gather, process, analyze, maintain, store, and disseminate data relating to OCS marine minerals. The MMIS supports development and distribution of the National Offshore Sand Inventory (NOSI). It is imperative BOEM knows where OCS marine mineral resources are available to effectively manage their use. The MMIS includes both historical and current sand and sediment information that supports BOEM’s role in the nation’s coastal resilience efforts. For more information, see BOEM’s website.
