Photosynthetically Active Radiation (PAR) Standard Deviation of Long-term Mean, 2002-2013 - Hawaii

Solar irradiance is one of the most important factors influencing coral reefs. As the majority of their nutrients are obtained from symbiotic photosynthesizing organisms, reef-building corals need irradiance as a fundamental source of energy. Seasonally-low irradiance at high latitudes may be linked to reduced growth rates in corals and may limit reef calcification to shallower depths than that observed at lower latitudes. However, high levels of irradiance can lead to light-induced damage, production of free radicals, and in combination with increased temperatures, can exacerbate coral bleaching. This layer represents the standard deviation of the 8-day time series of irradiance (mol/m2/day) from July 2002 to December 31, 2013. Irradiance is here represented by PAR (photosynthetically active radiation), which is the spectrum of light that is important for photosynthesis. Monthly and 8-day 4-km (0.0417-degree) spatial resolution data were obtained from the MODIS (Moderate-resolution Imaging Spectroradiometer) Aqua satellite instrument from the NASA OceanColor website (http://oceancolor.gsfc.nasa.gov).

The standard deviation of the long-term mean of PAR was calculated by taking the standard deviation over all 8-day data from 2002-2013 for each pixel. A quality control mask was applied to remove spurious data associated with shallow water, following Gove et al., 2013. Nearshore map pixels with no data were filled with values from the nearest neighboring valid offshore pixel by using a grid of points and the Near Analysis tool in ArcGIS then converting points to raster.

Species Distribution: Pygmy Sperm Whale - Hawaii

This dataset contains a collection of known point locations of pygmy sperm whales identified through direct human observation via shipborne surveys. This can be useful for assessing species abundance, population structure, habitat use, and behavior. This collection is aggregated from multiple survey periods. Each data point contains attributes for further information about the time and source of the observation. This dataset was compiled by the Pacific Islands Ocean Observing System (PacIOOS) and may be updated in the future if additional data sources are acquired.

Cascadia Research Collective (CRC) has been undertaking shipborne surveys for odontocetes in Hawaiian waters since 2000. Pygmy sperm whales have been sighted much less frequently in Hawaiian waters than dwarf sperm whales.

NOAA Shallow-Water Benthic Habitats: Northwestern Hawaiian Islands: French Frigate Shoals

Benthic habitat maps for the nearshore, shallow (< 30 m) coastal waters of French Frigate Shoals in the Northwestern Hawaiian Islands (NWHI) and the Papahanaumokuakea Marine National Monument. NOAA's National Centers for Coastal Ocean Science (NCCOS) produced these data to support coral reef research and management. Habitat regions were digitally identified using visual interpretation of orthorectified satellite imagery with a minimum mapping unit (MMU) of approximately 100 square meters (1/40 acre).

A slightly different benthic habitat classification scheme was used for the NWHI compared to the Main Hawaiian Islands (MHI) and other regions across the Pacific (e.g., American Samoa, Guam, and CNMI). While many classes are similar, they are not categorized as biological cover types, geomorphological structure types, and geographic zones. Instead, a hierarchical scheme was used to flexibly denote substrate category (e.g., unconsolidated and hardbottom), structure (e.g., linear reef or pavement), and cover (e.g., coral, coralline algae, or macroalgae).

A total of 45 detailed benthic habitat classes were identified within the NWHI. For simplification and to more easily distinguish cover types, these are presented in a set of 7 aggregated benthic habitat classes including 5 hardbottom substrate classes (live coral, coralline algae, macroalgae, uncolonized, and unknown biological cover) and 2 unconsolidated substrate classes (macroalgae and uncolonized). Query an aggregated polygon to get the detailed benthic habitat classification at the clicked location.

Fish Replenishment Areas - Big Island, Hawaii

Boundaries of fish replenishment areas (FRA) along the leeward (west) coast of Big Island in Hawaii. In order to replenish populations of heavily collected aquatic species, a network of FRAs comprising 35% of the coastline were established by the State of Hawaii in 1999 through the West Hawaii Regional Fisheries Management Area (FMA), administered by Hawaii's Division of Aquatic Resources (DAR). Though fishing is permitted (with some restrictions on lay net fishing), aquarium collecting is prohibited in these areas.

Sea Surface Temperature (SST) Average Annual Maximum Anomaly, 2000-2013 - Hawaii

Sea surface temperature (SST) plays an important role in a number of ecological processes and can vary over a wide range of time scales, from daily to decadal changes. SST influences primary production, species migration patterns, and coral health. If temperatures are anomalously warm for extended periods of time, drastic changes in the surrounding ecosystem can result, including harmful effects such as coral bleaching. This layer represents the annual average of the maximum anomaly of SST (degrees Celsius) from 2000-2013.

Three SST datasets were combined to provide continuous coverage from 1985-2013. The concatenation applies bias adjustment derived from linear regression to the overlap periods of datasets, with the final representation matching the 0.05-degree (~5-km) near real-time SST product. First, a weekly composite, gap-filled SST dataset from the NOAA Pathfinder v5.2 SST 1/24-degree (~4-km), daily dataset (a NOAA Climate Data Record) for each location was produced following Heron et al. (2010) for January 1985 to December 2012. Next, weekly composite SST data from the NOAA/NESDIS/STAR Blended SST 0.1-degree (~11-km), daily dataset was produced for February 2009 to October 2013. Finally, a weekly composite SST dataset from the NOAA/NESDIS/STAR Blended SST 0.05-degree (~5-km), daily dataset was produced for March 2012 to December 2013.

The SST average annual maximum anomaly was calculated by taking the average of the annual maximum SST values in exceedance of the maximum monthly climatological SST from 2000-2013 for each pixel.

Hard-Soft Seafloor Classification, 40m - Swains, American Samoa

Preliminary hard and soft seafloor substrate map derived from an unsupervised classification of multibeam backscatter and bathymetry derivatives at Swains Island, American Samoa. The dataset was created from gridded (40 m cell size) multibeam bathymetry derivatives collected aboard R/V AHI, and NOAA ship Hi'ialakai; two scales of bathymetric variance and bathymetric rugosity. Backscatter data were from a 300 kHz Simrad EM300 and a 240 kHz Reson 8101 sonar, gridded at 5 m. Very limited seafloor photographs for groundtruthing are available for Swains Island and therefore no supervised classification was performed and we are unable to visually or empirically evaluate the accuracy of the unsupervised classification seafloor substrate map. However, in locations such French Frigate Shoals, NWHI, and Tutuila, American Samoa, where ground truth data are available, the unsupervised classification method is a robust predictor of substrate type in similar depth ranges and seafloor environments. Since groundtruthing was not used to validate the unsupervised classification at Swains Island extreme caution should be used when examining these data to locate habitat of biological significance. The map should be used in conjunction with bathymetric derivatives such as rugosity, slope, and Bathymetric Position Index (BPI).
