The Nature Conservancy (TNC) is an international, non-profit conservation organization that works to protect ecologically important lands and waters for nature and people around the world. In Hawaii, TNC has worked with partners and members for 30 years to protect more than one million acres of critical natural lands. The TNC Hawaii Marine Program was launched in 2001 to restore and protect the near-shore coral reefs and marine resources surrounding Hawaii.

Locations of known and historic fish ponds on the island of Hawaii (Big Island). For some fish ponds, data includes their condition, ownership, and references used to map them.

The purpose of this project is to assess the abundance of coral reef fish species inside and outside of two marine managed areas through detailed in-water surveys at 150 sites.

Proposed marine reserve area at Kaupulehu in the northern part of the Kona district on the west coast of Hawaii Island. The community proposal includes no-take for 10 years to allow for the reef to rest and replenish.

The Nature Conservancy (TNC) collects multiple data types at Kiholo Fishpond, including invasive vegetation, larval fish, sediment points, water quality monitoring, and water level.

To understand and mitigate the impacts of land-based pollution on coral reef health, The Nature Conservancy (TNC), University of Hawaii at Hilo (UH), and other researchers collected data to: 1) identify where high groundwater flows occur on the Puako reef system; 2) determine what is in the water by monitoring levels of bacteria and nutrients; and 3) assess whether degraded water quality can compromise coral health - and if so, which sites are most vulnerable.

Geology of the eight major islands of the State of Hawaii, a useful guide to its geologic setting and history, ground- and surface-water resources, economic deposits, and landslide or volcanic hazards. Maps the lithologic characteristics and distribution of geologic deposits and their stratigraphic relationships, including radiometric ages and geochemical analyses compiled from findings published over the past 100 years. Data compiled in 2007 by the United States Geological Survey (USGS) from multiple sources.
