Coral Reef Project: Maui Active
As part of USGS Coral Reef Project studies, the USGS has been heavily involved in efforts to improve the health and resilience of Maui's coral reef system, bringing expertise in mapping, circulation and sediment studies, and seismic surveys.
Overview
Maui is located 15 km (9 mi) east of Molokaʻi and 15 km northwest of Lānaʻi. Known as the Valley Isle, it encompasses 1883 sq km (727 sq mi), making it the second largest of the main eight Hawaiian Islands. A fringing reef surrounds much of the island. However much of the live coral growth can only be found on the leeward west coast where the reef is protected from waves by the surrounding islands. Reef growth is limited on the windward northeast coast due to wave impacts.
Motivation
Over the past two decades, there has been a notable change in seafloor-bottom type along west-central Maui, Hawaiʻi. Once dominated by abundant coral coverage, the area is now characterized by an increased abundance of turf algae and macroalgae. In an effort to improve the health and resilience of the coral reef system, the State of Hawaiʻi established the Kahekili Herbivore Fisheries Management Area. In addition, the U.S. Coral Reef Task Force (USCRTF) Watershed Partnership Initiative selected the Kaʻanapali region of west-central Maui as the site of the second national priority study area on which to focus its research and restoration efforts. The USGS has been involved heavily in these studies, bringing expertise in mapping, circulation and sediment studies, and seismic surveys. Other collaborators include the Environmental Protection Agency (EPA), NOAA, University of Hawaiʻi, University of Washington, University of California, Santa Cruz, and The Nature Conservancy.
The Hawaiian island of Maui is just one of the USGS Coral Reef Project's study locations.

The insular shelves of the southern coasts of the islands of Oahu and Molokai, and the western coast of Maui in the Hawaiian Archipelago were surveyed using ship-towed video between June 26 and July 11, 2002, as part of USGS-CMG cruise A-2-02-HW (Figure 1.1). The goals of the survey were to collect underwater video of the sea floor to: (1) Characterize substrate type and benthic habitat distributiAuthorsAnn Gibbs, Eric E.

Part IV: Measurements of waves, currents, temperature, salinity and turbidity in Honolua Bay, northwest Maui: 2003-2004
High-resolution measurements of waves, currents, water levels, temperature, salinity and turbidity were made in Honolua Bay, northwest Maui, Hawaii, during 2003 and 2004 to better understand coastal dynamics in coral reef habitats. Measurements were acquired through two different collection methods. Two hydrographic survey cruises were conducted to acquire spatially-extensive, but temporally-limitAuthorsCurt D. Storlazzi, M.

High-resolution measurements of currents, temperature, salinity and turbidity were made over the course of three months off West Maui in the summer and early fall of 2003 to better understand coastal dynamics in coral reef habitats. Measurements were made through the emplacement of a series of bottom-mounted instruments in water depths less than 11 m. The studies were conducted in support of the UAuthorsCurt D.

The U.S. Geological Survey (USGS) is working closely with academic institutions and state and Federal agencies to assess the factors that affect the health of Hawaii's and our Nation's coral reefs. In order to establish a basis from which scientists can objectively detect changes in reef health, the USGS and its cooperators are applying many new techniques to the mapping and monitoring of coral reAuthorsM.E.
