The MHK Atlas is an interactive mapping tool designed and developed by the National Renewable Energy Laboratory (NREL) to help explore potential for marine and hydrokinetic resources. The MHK Atlas was initially developed in order to visually represent the results of the EPRI’s Mapping and Assessment of the United States Ocean Wave Energy Resource and Lockheed Martin’s Ocean Thermal Extractable Energy Visualization (OTEEV). The MHK Atlas has been revised several times, which appended new layers and data, including: Riverine Hydrokinetic Resources, Ocean Current Power and Tidal Stream Power.
Instructions for using the tool (including how to use the map layers and how to download data) are available from the MHK Atlas website.
Wave energy potential is mapped along U.S. coastlines, including Hawaii, Puerto Rico and portions of Alaska. App users can explore several variables used in the wave energy assessment such as: wave power density, wave height, wave energy period, and wave hindcast direction. Data for each variable can be viewed as annual or monthly averages. OTEC and SWC resources are mapped globally. Available data layers can display numerous variables used in the assessment including: net power, delta-t, sea surface temperature, plant spacing estimates and the depth at which specified water temperatures can be found for sea water cooling. The assessment data can also be used in conjunction with political boundaries, such as Exclusive Economic Zones (EEZ).
