Hawaii ESI: M_MAMMAL (Marine Mammal Polygons)

Published by Office of Response and Restoration | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 19, 2025 | Last Modified: 2001-11-01T00:00:00.000+00:00
This data set contains sensitive biological resource data for endangered Hawaiian monk seals, endangered humpback whales, and other whales and dolphins in coastal Hawaii. Vector polygons in this data set represent marine mammal distribution and Hawaiian monk seal pupping and haul-out sites. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer. This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Hawaii. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the M_MAMPT (Marine Mammal Points) data layer, part of the larger Hawaii ESI database, for additional marine mammal information.
