The population numbers roughly 4000 breeding females today, having rebounded from its near extinction in the early 1970s, with most of the nesting restricted to French Frigate Shoals in the remote and geologically ancient Northwestern Hawaiian Islands. A timeline is provided of the scientific monitoring for this population and associated data streams relating to morphometrics, maturity, nest dynamics, sex ratio, as well as population growth and viability.

  • Summary of 2016 Reef Fish Surveys Around Kahoolawe Island 1
    doi:10.7289/V5/DR-PIFSC-17-011 Summary of 2016 Reef Fish Surveys around Kahoolawe Island 1 Results and information presented here summarize data gathered by the Coral Reef Ecosystem Program (CREP) of NOAA’s Pacific Islands Fisheries Science Center and partners during 2 days of reef fish and habitat surveys around Kahoolawe Island in July/August 2016. Surveys were conducted as part of the NOAA National Coral Reef Monitoring Program. Surveys were conducted using a standard sampling design and method implemented by NOAA’s Pacific Reef Assessment and Monitoring Program (Pacific RAMP) since 2009. In brief, pairs of divers record numbers, sizes, and species of fishes inside adjacent 15m-diameter ‘point- count’ cylinders and estimate benthic cover by functional groups (e.g. ‘coral’, ‘sand’). Because it is unpopulated and protected, Kahoolawe is an important reference location in in the main Hawaiian Islands and may also be a significant source of larvae and fish recruits for other parts of Maui-nui and perhaps beyond. Therefore, CREP hopes to routinely survey Kahoolawe reefs during future monitoring efforts. However, as 2016 was the first year for Kahoolawe surveys, we have a relatively small sample size there - 24 sites - in comparison to other Main Hawaiian Islands (MHI: between 107 and 257 survey sites per island). Main conclusions and observations: • Reef fish biomass was high at most sites we visited in Kahoolawe, with mean island-wide biomass higher than at any other of the MHI, although only marginally higher than at Niihau. Biomass tended to be slightly higher at sites along the southern section of the island.

  • Photographing the Islands of Hawaii
    Molokai Sea Cliffs - Molokai, Hawaii Photographing the Islands of Hawaii by E.J. Peiker Introduction to the Hawaiian Islands The Hawaiian Islands are an archipelago of eight primary islands and many atolls that extend for 1600 miles in the central Pacific Ocean. The larger and inhabited islands are what we commonly refer to as Hawaii, the 50 th State of the United States of America. The main islands, from east to west, are comprised of the Island of Hawaii (also known as the Big Island), Maui, Kahoolawe, Molokai, Lanai, Oahu, Kauai, and Niihau. Beyond Niihau to the west lie the atolls beginning with Kaula and extending to Kure Atoll in the west. Kure Atoll is the last place on Earth to change days and the last place on Earth to ring in the new year. The islands of Oahu, Maui, Kauai and Hawaii (Big Island) are the most visited and developed with infrastructure equivalent to much of the civilized world. Molokai and Lanai have very limited accommodation options and infrastructure and have far fewer people. All six of these islands offer an abundance of photographic possibilities. Kahoolawe and Niihau are essentially off-limits. Kahoolawe was a Navy bombing range until recent years and has lots of unexploded ordinance. It is possible to go there as part of a restoration mission but one cannot go there as a photo destination. Niihau is reserved for the very few people of 100% Hawaiian origin and cannot be visited for photography if at all. Neither have any infrastructure. Kahoolawe is photographable from a distance from the southern shores of Maui and Niihau can be seen from the southwestern part of Kauai.

  • Spiders of the Hawaiian Islands: Catalog and Bibliography1
    Pacific Insects 6 (4) : 665-687 December 30, 1964 SPIDERS OF THE HAWAIIAN ISLANDS: CATALOG AND BIBLIOGRAPHY1 By Theodore W. Suman BISHOP MUSEUM, HONOLULU, HAWAII Abstract: This paper contains a systematic list of species, and the literature references, of the spiders occurring in the Hawaiian Islands. The species total 149 of which 17 are record­ ed here for the first time. This paper lists the records and literature of the spiders in the Hawaiian Islands. The islands included are Kure, Midway, Laysan, French Frigate Shoal, Kauai, Oahu, Molokai, Lanai, Maui and Hawaii. The only major work dealing with the spiders in the Hawaiian Is. was published 60 years ago in " Fauna Hawaiiensis " by Simon (1900 & 1904). All of the endemic spiders known today, except Pseudanapis aloha Forster, are described in that work which also in­ cludes a listing of several introduced species. The spider collection available to Simon re­ presented only a small part of the entire Hawaiian fauna. In all probability, the endemic species are only partly known. Since the appearance of Simon's work, there have been many new records and lists of introduced spiders. The known Hawaiian spider fauna now totals 149 species and 4 subspecies belonging to 21 families and 66 genera. Of this total, 82 species (5596) are believed to be endemic and belong to 10 families and 27 genera including 7 endemic genera. The introduced spe­ cies total 65 (44^). Two unidentified species placed in indigenous genera comprise the remaining \%. Seventeen species are recorded here for the first time. In the catalog section of this paper, families, genera and species are listed alphabetical­ ly for convenience.

The IBA Program was initiated by BirdLife International in Europe in the 1980's. Since then, over 8,000 sites in 178 countries have been identified as Important Bird Areas, with many national and regional IBA inventories published in 19 languages. Hundreds of these sites and millions of acres have received better protection as a result of the IBA Program. As the United States Partner of BirdLife International, the National Audubon Society administers the IBA Program in the U.S., which was launched in 1995 (see http://www.audubon.org/bird/iba/index.html). Forty-eight states have initiated IBA programs, and more than 2,100 state-level IBAs encompassing over 220 million acres have been identified across the country. Information about these sites will be reviewed by the U.S. IBA Committee to confirm whether they qualify for classification as sites of continental or global significance.

A spline interpolation scheme ~s utilized to convert the actual soundings of the island bathymetry to a 5.5 km square grid closely approximating the topography of the islands. A time-marching, central difference, explicit scheme is used to evaluate the wave field by the linear, long wave, Eulerian equations of motion and continuity ~n Cartesian coordinates for a frictionless, homogeneous fluid. The condition of no normal flow is employed at the island shorelines and a localized interpolation technique is utilized at the outer boundary to simulate a free-flow boundary.

FARMERI, MARIA C. FARMER2 and RAINER BERGER3 ABSTRACT. Extensive eruptions of alkalic basalt from low-elevation fissures and vents on the southern flank of the dormant volcano, Cerro Evermann, accompanied the most recent phase of volcanic activity on Socorro Island, and created 14C the Lomas Coloradas, a broad, gently sloping terrain comprising the southern part of the island. We obtained ages of 4690 ± 270 BP (5000-5700 cal BP) and 5040 ± 460 BP (5300-6300 cal BP) from lacustrine deposits that occur within volcanic sequences of the lower Lomas Coloradas. Apparently, the sediments accumulated within a topographic depression between two scoria cones shortly after they formed. The lacustrine environment was destroyed when the cones were breached by headward erosion of adjacent stream drainages.
