Introduction to Mid-Atlantic Humpback Whale Catalog

Overview of the Project

The Mid-Atlantic Humpback Whale Catalog (MAHWC) was initially developed as a collaborative project among numerous experts and contributors including

Allied Whale,
Center for Coastal Studies,
HDR, Inc.,
Rudee Tours, Whale and Dolphin Conservation,
Wildlife Conservation Society, and

as well as many individuals associated with those organizations.

Funding support for development was provided by United States Navy Fleet Forces Command under the U. S. Navy's Marine Species Monitoring Program. In-kind funding and primary project oversight was provided by the Virginia Aquarium & Marine Science Center Foundation's Research & Conservation Section. HDR, Inc. provided contractual support and technical expertise, as well as contributing data to the catalog. Kim Urian at Duke Marine Lab and the Duke University Marine Geospatial Lab provided online catalog design and implementation expertise through the OBIS-SEAMAP web portal. Additional organizations have or will be contributing images and data as the catalog matures.
