The Orange Keyhole Sponge, Mycale armata Thiele, was unknown in Hawaii prior to 1996. First reported in Pearl Harbor, it now occurs in virtually every commercial harbor in the main Hawaiian islands, where it can be a major component of the fouling community on harbor piers and jetties. It has been reported from a few coral reef locations near harbors, but in Kaneohe Bay it has become a major component of the benthic biota in the south bay in the last 5-10 years. A study was conducted in 2004-2005 to determine Mycale armata's distribution, abundance throughout the bay, its growth rates on permanent quadrats, and whether mechanical removal would be an effective management technique for its control. Results from 190 manta board surveys on 28 reefs and paired 25 m belt transects using photo quadrats on 19 reefs indicated that the sponge had maximal coverage in the south-central part of the bay, in the vicinity of Coconut Island.

Surveys for adult invertebrates that were part of the hull fouling communities were done to determine to what extent marine alien invasive species (AIS) are being transported in this fashion. The focus was to perform a qualitative analysis that created a species inventory. The organisms that generally foul vessel hulls are the typical species found in natural marine intertidal and subtidal fouling communities. These organisms are usually associated with one of the following groups: porifera (sponges), coelenterata (hydroids, corals and anemones), mollusca (mussels, clams, and sea slugs), annelida (marine worms), arthropoda (barnacles, amphipods, and crabs), bryozoa (moss animals), chordata (sea squirts and fish), as well as macroalgae (seaweed). Through collaboration with state and private industry representatives, arrivals notification for various vessel types was received. This arrivals information was used to schedule field survey activities throughout the study. Field work occurred in 2003 at harbors of southern and southwestern coasts of Oahu, Hawaii.

In an effort to detect spatial and temporal changes in the structure of the coral reef community, coral coverage and reef fish density and diversity were documented at selected sites along the coastline of the Big Island of Hawaii using standard transect methodology and SCUBA. The data were collected as training for students within the Quantitative Underwater Ecological Surveying Techniques (QUEST) Program of the Kalakaua Marine Educational Center at the University of Hawaii at Hilo. Several sites have been established. This database contains surveys for Puako and Mahukona from 1992 - 1999. Because of the disparity of experience among the student observers, this data set contains a much higher margin of error than like surveys by professional coral reef scientists.

Chlorophyll data were collected from a sewage outfall site in Kaneohe Bay, Hawaii, from 1982 to 2001. The purpose of the project was to study the responses of the ecosystem to the sewage diversion from the inner bay to an offshore, deep water location and to continue monitoring the location to denote changes associated with natural environmental and anthropogenic forcing on the primary productivity. Data were submitted by the University of Hawaii at Manoa and funding was provided by the Environmental Protective Agency (EPA).

Shore-based belt and habitat quadrats were surveyed using transects at 1 to ~5 m depths at a total seven (7) sites: at (1-2) 2 longshore sites on the leeward coast (South Kohala district) of the Big Island (Hawaii Island) in the MHI during spring 2006 and spring-summer 2007 (spring 2007 only for predator belt transects); (3) at 1 site-group comprising multiple patch reefs located throughout north, central and south Kaneohe Bay, windward Oahu in the MHI during spring 2007; (4-5) at 2 longshore sites on the back reef of Midway Atoll in the NWHI during spring 2006 and spring-summer 2007; and (6-7) at 2 site-groups comprising multiple patch reefs within the Welles Harbor region of the lagoon of Midway Atoll during spring-summer 2007. For predator reef fish surveys, from 12-20 randomly positioned transects were surveyed at each site or site-group in a given year. Raw survey data consist of species-specific and size-specific numerical counts of large juvenile and adult stages of PREDATOR reef fishes encountered within transect boundaries. For recruit reef fish surveys, from 12-25 randomly positioned transects were surveyed at each site or site-group in a given year. Raw survey data consist of species-specific and size-specific numerical counts of recruit reef fishes encountered within transect boundaries. Quadrat surveys consisted of two types: "Reference" quadrats (whose positions were randomly selected) and "Target" quadrats (positions centered on sightings of recruit fishes). In each quadrat, the benthic cover of each of ten (10) major substratum types were estimated, as was a "Rugosity Index" based on the ratio of conforming-to-straight line distances along both major axes of the quadrat.

Kaneohe and Waimanalo streams on the windward side of the island of Oahu in the Hawaiian Islands have been hardened to prevent flooding. The hardening process has involved elimination of the natural riparian habitat and replacement of the natural stream channel with a concrete-lined conduit having vertical walls and a broad, flat bottom. The shallow depth of the water column and the absence of shade have resulted in temperatures that average as much as 4-5oC above ambient and rise as high as 32oC during daylight hours. Unlike most low-order streams, the hardened sections of both streams are autotrophic, as evidenced by elevated pH values and O2 concentrations as high as 150% of saturation. Several allochthonous inputs, one from a storm sewer and the other from a natural spring, introduced water with anomalously low O2 concentrations and very high nitrate concentrations. The absence of sediments in the hardened sections of the streams precludes natural sedimentary microbial processes, including denitrification. Nitrate concentrations in a section of Waimanalo Stream with a natural streambed drop dramatically from values in excess of 400 ?M to concentrations less than 10 ?M at the head of the estuary. Although some of this decline is due to dilution with seawater, the concentration of nitrate at the head of the estuary is only 10% of the value that could be explained by dilution effects. Biological processes associated with a natural streambed thus appear very important to the functionality of the streams and in particular to their ability to process allochthonous nutrient inputs in a way that minimizes impacts on the nearshore environment. Prevention of flooding can be accomplished by mechanisms that do not involve elimination of riparian buffer zones and destruction of channel habitat. To maintain water quality and stream functionality, it will be important that these alternative methods of flood control be utilized. Converting natural streams to storm sewers is an unenlightened way to address flooding problems.

Data in this set come from two studies: "Ability of protected reefs to resist alien algae" and "How many fish does it take to keep the alien algae out?" Both are authored by Ms. Danielle Jayewardene and Dr. Charles Birkeland of University of Hawaii Manoa, in 2005 and 2006, respectively. For the former, the goal was to objectively and quantitatively assess the ability of marine protected areas (MPAs), to maintain ecosystem health, and to thereby resist invasion of alien algae. For the latter, specific objectives involved a) determining whether there are differences in cropping ability by larger herbivorous fishes compared to smaller herbivorous fishes, and b) whether there is a threshold level of algal biomass above which even an increased number of herbivorous fishes simply cannot crop down. The field work took place at eight coral reef sites located on the island of Oahu and the island of Hawaii.

The National Oceanographic and Atmospheric Administration's (NOAA) Undersea Research Center at the University of North Carolina at Wilmington (NURC/UNCW) coordinated an acoustic survey in portions of the Oculina Habitat Area of Particular Concern from June 14-19, 2005. This metadata record is the parent record for this multi-beam echosounder (MBES) survey, which includes the following products: 1) bathymetric grid, 2) XYZ ascii table created from the grid, 3) colored coded shaded geotiffs from the grid, 4) backscatter mosaic, 5) XYA (amplitude) ascii table created from the mosaic, and 6) geotif of backscatter draped on the bathymetric grid. All products are available through an on-line Oculina Geographic Information system (www.uncw.edu/oculina) and on an OGIS CD. Some data sets are also posted on NOAA's Coral Reef Information System (CoRIS) at www.coris.noaa.gov. Another product that will not be distributed, but will be used as input to habitat classification software (QTC MultiView (website)), are raw data files logged to disk using the the Simrad EM3002 MBES data acquisition software. These raw files contain packets of information (depth soundings, navigation, attitude, sound velocity profiles, UTC time) that the acquisition software logged sequentially in time. The raw data format is available from Kongsberg-Simrad (website). The MBES system was provided by Seafloor Systems Inc. and the support vessel was UNCW's 70-ft. R/V Cape Fear. This survey is part of an on-going partnership effort funded by the NOAA Coral Reef Conservation Program (CRCP). This survey was funded by a CRCP grant to Andrew David, NOAA Fisheries - Panama City, and Andrew Shepard, NURC/UNCW. In addition to partners above, other partners include UNCW's Spatial Analysis Lab, US Geological Survey, and the S. Atlantic fishery Management Council.
