AbstractThe major cause of the Hawaiian Islands coastal erosion is shown to be not global warming, but the sinking of the volcanic islands. The geologic “circle-of-life” beyond the Hawaiian hot spot is the true explanation of the beach erosion. The sea levels are slow rising and not accelerating worldwide as well as in the United States. In the specific of the Hawaii Islands, they have been decelerating over the last 3 decades because of the phasing of the multi-decadal oscillations for this area of the Pacific. There is therefore no evidence coastal erosion will double in the Hawaii by 2050 because of global warming.

The 1960S

The TOPEX/POSEIDON satellite mission to observe the oceans triggered the formation of the new specialty of space oceanography from the 1970s to 1990s. Previously, in the 1960s in the United States, traditional oceanographers had shown little interest in the possibilities of space and thus space engineers and physicists worked on the first missions (Seasat in particular). TOPEX/POSEIDON brought together two projects, one American (TOPEX) and the other French (POSEIDON). The gradual crystallization of the disciplinary specialty of space oceanography occurred by making available a platform of instruments able to meet an ensemble of varied needs. Battery failures just before the launch of the joint mission meant that the mission had to focus on the essentials (notably El Niño effects). Subsequently, the discovery of a significant rise in sea levels due to global warming resulted in space oceanography becoming a recognized specialty. The case of TOPEX/POSEIDON shows the original ways in which instruments gained a place in the very large range of oceanographic techniques.

Alter Ego

AbstractFrom the perspective of studying natural hazards, the peace and tranquillity that might be expected from a literal translation of its name does not always capture the reality of life for communities on the Pacific Rim. This reality is more readily discerned in its alter ego: the Ring of Fire. The latter leaves one in less doubt as to the hazardous circumstances likely to prevail in this region. In addition to the hazards posed by the numerous volcanoes that resulted in the ‘Ring of Fire’ appellation, communities situated around the Pacific Rim also have to contend with earthquakes, tsunami, storms, cyclones/typhoons, flood and bushfire. To this list of acute events can be added hazards of a chronic nature such as salinity, environmental degradation and sea-level rise that represent growing threats to many Pacific Rim countries. The region also faces increased risk from health-related hazards. Sydney, for example, has been identified as a pandemic hotspot as a result of it being a hub linking the airways of Asia and the United States.

Abstract We show here the presence of significant “coldspot” of sea level rise along the West Coast of the United States and Canada (including Alaska). The 30-years sea level for the area are mostly falling also at subsiding locations as San Francisco and Seattle where subsidence is responsible for a long term positive rate of rise. The 20 long term tide gauges of the area of length exceeding the 60-years length have a naïve average rate of rise −0.729 mm/year in the update 30-Apr-2015, down from −0.624 mm/year in the update 14-Feb-2014. Therefore, along the West Coast of the United States and Canada the sea levels are on average falling, and becoming more and more negative.

Climate Refugees

This study aims to suggest another view of the so-called “climate refugee”, especially those from the Small Island Developing States (SIDS) in the Pacific Ocean. Although many studies have been conducted on the legal aspects of the climate refugees’ situations, little has been studied about how they succeed in re-establishing their livelihoods after relocation. Unlike migrations forced by other causes, the future migrations induced by sea level rise have a long lead time which gives the people involved the opportunity to develop the skills necessary to adjust to their new lives. This paper examines whether “pre-training” opportunities are sufficient in those countries from which climate refugees are most likely to come. The author focuses on the Republic of the Marshall Islands, one of the small island countries in the Pacific being threatened by environmental changes such as rising sea level, high tides, and drought. Due to a unique situation allowing the Marshallese people to move to the United States without a visa, many people do so each year under the free association partnership. However, some of these migrants fail to adjust to the United States and come back to their home islands, possibly due to a lack of skills. Given that more climate refugees are likely in the future, pre-training that provides essential skills to benefit future climate refugees is necessary. Through key informant interviews in the Marshall Islands, it seems that such training opportunities are currently limited, but have great potential to flourish.

Petrels collected by Titian Ramsay Peale in the Pacific Ocean during the United States Exploring Expedition of 1838–1842

The report by Titian Ramsay Peale on birds encountered during the Wilkes Expedition was withdrawn for inaccuracy when few copies had been distributed, and re-written by John Cassin. A survey of the accounts of the petrels shows that this was not an improvement. Two important type localities for Procellaria brevipes and Thalassidroma lineata are probably wrong, and could be exchanged.
