The Hunga Tonga-Hunga Ha'apai massive undersea volcanic eruption occurred on the 15th of January 2022 and led to an induced tsunami event. The eruption triggered a tsunami warning for several South Pacific island nations with rising water levels were reported on the coastline of Peru and the Pacific Coast in the United States and caused devastating impact across Tonga. In addition, volcanic ash residue was also visible on land surfaces including building structures and surrounding vegetation.
This dataset contains preliminary impact assessments of the Hunga-Tonga-Hunga-Ha'apai volcanic eruption and induced tsunami in January 2022.
The eruptions sent a plume of ash, gas and steam 20 kilometers (12.4 miles) into the air. Satellite imagery showed a massive ash cloud and shockwaves spreading from the eruption. Ash was falling from the sky in the Tonga capital, Nuku'alofa, Saturday evening and phone connections were down. The eruption was likely the biggest recorded anywhere on the planet in more than 30 years, according to experts.
This publication intends to assist project designers, regulators and decision makers to anticipate and address all relevant public health, socio‐economic and environmental concerns that may arise when under‐ taking a desalination project, for obtaining maximum beneficial use of the desalinated water in terms of quality, safety and environmental protection.

The Protected Area Forum's (PAF) outcome is that the forum will enable protected area practitioners, researchers, academics, private sector, potential donors and local communities who manage or support protected areas in PNG, to share their experiences, insights and any lessons learnt in relation to factors impacting protected areas. It will identify and formulate national priorities for effective protected area management in the country. The results of the forum will contribute to the implementation of the Protected Area Policy.
Stakeholder consultations were the most important aspect of achieving the marae moana legislation.

Recent studies have shown that many coral reefs are capable of
yielding a total fish catch of 18- 24 T.Km-2 (Hill, 1978; Alcala,
1981; Munro, 1987). There are, however, no estimates for the
productivity and yield of fishes associated with coral reefs in
French Polynesia. This study was designed to determine the fisheries yield from a part of the fringing reef on the island of Moorea, French Polynesia.

Coral reefs are vital ecosystems, providing a source of income, food arid coastal protection for millions of people; arid recent studies have shown that coral reef goods and services provide an annual net benefit of US$30 billion to economies worldwide
During the period February 13 to 20, 1973, a visit was made to Canton Island for the purpose of conducting a preliminary survey of marine turtle nesting populations. Although previous investigators have described the sea birds (Buddle, 1938; Murphy G., 1954), insects (Van Zwaluwenburg, 1943, 1955), and vegetation (Hatheway, 1955), very little is known about the marine environment of Canton or the other seven atolls (Enderbury, Birnie, Phoenix, Sydney, Hull, Gardner and McKean) which comprise the Phoenix group.
More than 20 cetacean species are known to exist in the
Pacific Islands Region, which encompasses the U.S. Exclusive
Economic Zone, or EEZ (waters out to 370 km from shore) around
the entire Hawaiian Archipelago. Johnston Atoll. Kingman Reef and Palmyra Atoll. Baker and Howland Islands. Jarvis Island. American Samoa. Wake Island, Guam, and the Commonwealth of the
Northern Mariana Islands, totaling some 5.8 million km2 of ocean.
Many of the species present are poorly studied throughout their

Microbenthos and macrobenthos were quantitatively studied at 62 stations distributed regularly over the Uvea Atoll lagoon (850 km2). Sampling was performed using both SCUBA and a 0.1 m2 Smith Mclntyre grab. Mean estimates of ATP, chlorophyll a and phaeopigments were 297.3ng/cm2, 77.01 mg/m2 and 35.28 mg/m2
respectively. The mean macrobenthic biomass was 4.14 gAFDW/m2 of which the macrophytobenthos accounts for 39%. The benthic biomass decreased from the coast to the deepest parts of the lagoon. Macrophytes were most abundant in the coastal area
France has an important role and extensive responsibilities in protecting the world's oceans. It is the world's third
largest maritime power with an Exclusive Economic Zone (EEZ) covering 11 million km2, and has the fourth
largest area of coral reefs representing biodiversity hotspots.
According to a recent Nature Conservancy assessment, only 1% of marine areas (as against 12 % of all land

There is a high level of uncertainty with the specific estimation of pollutant loads. A large body of work has
been completed that provided qualitative and quantitative data; however, the noting of data gaps and inherent uncertainties of the methods used have qualified much of the quantitative data. Much of the data are based on rapid assessment methods that utilise generic loading rates, assumed waste flow composition, typical production methods, local production rates. Unfortunately, production rate data are inconsistently available and are difficult to verify.
To date, few quantitative assessments of the marine resources of Palau have been conducted. For the off-shore tuna fishery, reasonable data time-series are available for the foreign access tuna fishery, but data for domestically based tuna operations are incomplete. For the near-shore fishery, reef resources are exploited by subsistence, commercial and recreational fishermen. Very few data are available that document trends in production for most reef-resident and reef-associated fisheries resources in Palau, except for the trochus fishery.
This report presents the results of a twelve day survey expedition (5 to 16 December, 2004) and represents the first ever systematic effort to document the marine biodiversity of the Great Sea Reef (GSR), locally known as Cakaulevu, to the north of Vanua Levu in the Fiji Archipelago. 23 sites were surveyed over 6 major habitat types: outer barrier reefs, back barrier reefs, channels, mangrove island fringing reefs, rocky island fringing reef and submerged patch reefs.

The Marshall Islands are critically dependent on the health of their coral reefs: every rock and sand grain on the islands are the remains of coral reef organisms. Only actively growing coral reefs can protect the islands against ocean waves and global sea level rise, and provide fish to feed the people. These crucial services are rapidly deteriorating because global warming is
The study of marine sediments provides useful information in marine, environmental and geochemical research about pollution of the marine environment (Calace et al. 2005). Urban developments and industrial activities contribute to the introduction of significant amounts of contaminants (among them trace metals) into the marine environment and affect directly the coastal systems where they are often deposited (Angelidis 1995; Dassenakis et al. 2003).
In general, leatherback turtles face serious threats at all life stages, both on the beaches where they nest and hatch and in the water where they spend most of their life time. Sea turtle eggs are collected for food, while in some areas juveniles and adults are hunted for their meat and oil. Habitats that are keys to their survival are rapidly being degraded due to coastal development. They are also killed in great numbers as incidental catch, or by catch, in fisheries.
