Robinson Publication_Date: 2004 Title: Maps of Hawaiian Islands Exclusive Economic Zone Interpreted from GLORIA Sidescan-Sonar Imagery Geospatial_Data_Presentation_Form: map Series_Information: Series_Name: Scientific Investigation Map Issue_Identification: SIM-2824 Publication_Information: Publication_Place: Menlo Park Publisher: U.S. Geological Survey Description: Abstract: The Hawaiian Islands form the southeast leg of a 5,000-km-long string of underwater and subaerial volcanoes called the Hawaiian-Emperor Chain. Volcanoes of the Hawaiian Islands form part of a long, discontinuous ridge known as the Hawaiian Ridge (Clague and Dalrymple, 1987). In 1983, the United States defined an Exclusive Economic Zone (EEZ) around the Hawaiian Islands extending from the coastline to 200 nautical miles offshore. The U.S. Geological Survey (USGS) had the primary responsibility to map this zone and in 1984 began the EEZ-SCAN program to systematically map the EEZ at a reconnaissance scale. For assistance with the data collection, the USGS partnered with the Institute of Oceanographic Sciences (IOS) of the United Kingdom. The IOS developed a long-range side-scan-sonar system well suited to this purpose. This system, called GLORIA (Geologic LOng-Range Inclined ASDIC, where ASDIC is another acronym for SONAR, SOund NAvigation Ranging), is capable of imaging a swath of sea floor 40 km wide with each pass of the ship. The map is derived from GLORIA data collected in 1986-1989 from the southeastern Hawaiian Ridge EEZ, which covers more than 1,000,000 km2 of sea floor (Groome and others, 1997). The Hawaiian Islands cap the northwest-southeast-trending ridge. Purpose: The U.S. Geological Survey (USGS) had the primary responsibility to map this zone and in 1984 began the EEZ-SCAN program to systematically map the EEZ at a reconnaissance scale. This map displays the geologic materials around the Hawaii Islands.

Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:2,000,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:2,000,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data. Acknowledgement of the U.S. Geological Survey would be appreciated in products derived from these data.

The position of each data item is derived from the USGS GLORIA sidescan-sonar dataset, and therefore additional inaccuracies arising from inaccuracies in the base map may also be encountered.
