Effects of Pelagic Longline Fishing on Seamount Ecosystems Based on Interviews with Pacific Island Fishers
Effects of Pelagic Longline Fishing on Seamount Ecosystems Based on Interviews with Pacific Island Fishers This publication was prepared by IUCN as a part of the Oceanic Fisheries Management Project, funded by the Global Environment Facility, through the United Nations Development Program. The Project aims to achieve global environmental benefits by enhanced conservation and management of transboundary oceanic fishery resources in the Pacific Islands region and the protection of the biodiversity of the Western Tropical Pacific Warm Pool Large Marine Ecosystem. It is executed by the Pacific Islands Forum Fisheries Agency in conjunction with the Secretariat of the Pacific Community and IUCN. Website: http://www.ffa.int/gef/.

Pelagic Fisheries Research Program (PFRP) Over the Period 1993–2003
Research and writing: Noreen M. Parks Editing: John Sibert Layout:May Izumi Cover Photo: Richard Herrmann ~ UH-NOAA~ Executive Summary This report highlights the accomplishments of the Pelagic Fisheries Research Program (PFRP) over the period 1993–2003. Operating from the University of Hawaii-Manoa, the program supports the scientific research needs of the Western Pacific Regional Fishery Management Council, in conjunction with the National Oceanic and Atmospheric Administration. More than 70 projects have been funded to address questions in fisheries biology, oceanography, statistics and modeling, genetics, protected species, fish- eries economics and socio-cultural issues. The PFRP has played a leading role in promoting research in support of the ecosystem approach to fisheries. Through its links with the University of Hawaii, the PFRP is able to assist in training new fisheries scientists. In its scientific collaborations and partic- ipation in multinational forums for fisheries management, the PFRP also has played an important role in fostering international cooperation for the sustainable management of pelagic fisheries throughout the central and Western Pacific. Responding to emerg- ing scientific needs for responsible fisheries stewardship, the program continues to sponsor cutting-edge, multidisciplinary research. i ii THE PACIFIC OCEAN—HEART OF THE BLUE PLANET, HOME TO THE WORLD’S RICHEST FISHERIES If you hitched a ride on a space shuttle circling the globe, during much of the voyage the Pacific Ocean would dominate your view of Earth. Our “blue planet” owes much of its liquid character to the Pacific, which covers nearly one third of the globe—an area larger than all the landmasses combined. -
Glossary for Hawaiian and Other Polynesian Terms
Glossary for Hawaiian and Other Polynesian Terms Pronunciation Hawaiian vowels are as in English: a, e, i, o, and u. But with respect to pronunciation, the letter “a” is pronounced as the soft ah sound in papa; “e” as the ā sound in play; “i” as the ē sound in need; “o” as used in bowl; and “u” as the ew sound in tune. Diacritical marks are used to indicate stress on particular vowels, and as glottal stops. Te macron (called kahakō in Hawaiian) is used to stress and elongate any of the vowel sounds. For example, the ā sound in pāhoe- hoe (sheet lava) is stressed and lengthened, as in pahh-ho-ay-ho-ay. Te reverse apostrophe (called an okina in Hawaiian) is used as a glot- tal stop, as in the closed throat sound that should precede formation of the word ‘ahi (pronounced ah-hee), or between sounds, as in Punalu‘u (pronounced poo-nah-lew-ew). Certain vowel combinations (diph- thongs) are also pronounced in a manner dissimilar to the way they are pronounced in English, with stress on the frst vowel. For instance, the “ou” sound in Hawaiian is pronounced with stress on the o, as in pouli © Te Editor(s) (if applicable) and Te Author(s), under exclusive license 247 to Springer Nature Switzerland AG 2019 E.

FINAL REPORT Collaborative Research with the Sitka Sound
FINAL REPORT Sitka Sound Science Center Collaborative Research with the Sitka Sound Science Center and the Geological Survey of Canada to Investigate Recent Deformation Along the Queen Charlotte- Fairweather Fault System in Canada and Alaska, USA Reference: FY2015 EHP Program Grant G15AP00034 PIs: H. Gary Greene and J. Vaughn Barrie February 2017 Abstract This NEHRP study was designed to investigate the Queen Charlotte-Fairweather (QC- FW) fault system, which is the active transform boundary between the Pacific Plate and the North American Plate, using the Canadian Coast Guard Ship (CCGS) John P. Tully to collect geophysical data and seafloor photographs, core and grab samples. The primary objective of the study was to identify and map piercing points such as channels and gullies that could be used to estimate offset along faults of the Queen Charlotte (QC) fault zone and date fault movement using datable material within the collected piston cores to determine slip rates. To this end the cruise was extremely successful as we were able to identify at least four erosional features such as a canyon and three gullies that consistently exhibited approximately 800 m ±50 m offsets along the central segment of the QC fault zone. Using an age of 14.5 ±0.5 ka for the complete retreat of the last major glacial advance established by Barrie and Conway (1999) and the youngest dates of the sediments recovered in cores of the piercing points at approximately 17 ka, we estimate a slip rate of approximately 55 mm/yr, similar to slip rates calculated by Brothers et al. -
Maps of Hawaiian Islands Exclusive Economic Zone Interpreted From
DISCUSSION The Hawaiian Islands form the southeast leg of a 5,000-km-long string of underwater and subaerial volcanoes called the Hawaiian-Emperor Chain (fig. 1, map sheet, inset). Volcanoes of the Hawaiian Islands form part of a long, discontinuous ridge known as the Hawaiian Ridge (Clague and Dalrymple, 1987). In 1983, the United States defined an Exclusive Economic Zone (EEZ) around the Hawaiian Islands extending from the coastline to 200 nautical miles offshore (fig. 2, map sheet). The U.S. Geological Survey (USGS) had the primary responsibility to map this zone and in 1984 began the EEZ- SCAN program to systematically map the EEZ at a reconnaissance scale. For assistance with the data collection, the USGS partnered with the Institute of Oceanographic Sciences (IOS) of the United Kingdom. The IOS developed a long-range side-scan-sonar system well suited to this purpose. This system, called GLORIA (Geologic LOng-Range Inclined ASDIC, where ASDIC is another acronym for SONAR, SOund NAvigating Ranging), is capable of imaging a swath of sea floor 40 km wide with each pass of the ship (fig. 3). The map is derived from GLORIA data collected in 1986-1989 from the southeastern Hawaiian Ridge EEZ, which covers more than 1,000,000 km2 of sea floor (fig. 2; Groome and others, 1997). The Hawaiian Islands cap the northwest-southeast-trending ridge. Over the past 80 m.y., the Hawaiian-Emperor Chain developed, one volcano after another, as the Pacific Plate moved slowly northwestward over a stationary hot spot. At the hot spot, magma from the Earth’s mantle continually rises through the ocean crust, and lava erupts frequently to slowly build a volcanic seamount. -
