Cenozoic mollusks from seven island groups in the western Pacific are treated systematically. The islands form a broad belt spreading 4,000 miles across tropical latitudes from the Mariana Islands and Palau on the northwest through the Marshall, Ellice and New Hebrides groups to Fiji and Tonga on the southeast. Each of the island groups has a section of Quaternary limestones and all except the Ellice group are known to have a Tertiary sequence as well. The known Tertiary in all island groups, except that in the New Hebrides, extends back as far as the Eocene. No Paleocene rocks have been recognized. Two hundred and eight species and subspecies are described. These include representatives of 3 families of chitons and 16 families of gastropods (Haliotidae through Adeorbidae). Three new subgenera of gastropods are described: Vitiastraea (subgenus of Astraea), Subditotectarius (subgenus of Tectarius), and Ailinzebina (subgenus of Zebina). Sixty-seven new species and five new subspecies are described. The species discussed in the present report comprise approximately one-sixth of available collections. About three-fourths of the new forms were recovered from the drill holes in the Marshall Islands; the remainder, from outcrop samples, are divided almost equally between Palau and Fiji. A few of the new forms from the Marshall Islands also occur in Palau and Fiji. The richest and most widespread assemblages are Miocene (Tertiary / and g). Most of the mollusks are reef associated. Many, notably those of the limestones in the deep drill holes of the Marshall?, occur in beds that were deposited in lagoons; some species occur in beds that were accumulated on tidal flats; a few species lived in fresh or brackish waters. The assemblages of fossil mollusks, like those living in the area today, are Indo-Pacific in general aspect. The strongest discernible ties are with living and fossil faunas of tropical Indonesia, rather than with faunas from more southerly areas (southern Australia and New Zealand) or more northerly areas (the Ryukyu Islands and Japan). Thirty-throe of the des-ribed species that still live in the island area have been there at least since late Tertiary time. Of this group, the shells of 25 were recovered from Marshall Island drill holes, those of 10 from outcrops in Fiji. A few species that lived in the island area during the Tertiary are now living only in other parts of the Indo-Pacific region. Numerous living Indo-Pacific species had close relatives, some perhaps ancestral, in the island area during the upper Tertiary. In the Miocene of Bikini is a species of Pisulina, a genus known previously only from a few species living near India and Ceylon. The neanvt relatives of a lower Miocene CtjniNcn of Eniwetok live off the Capo of Ciood Hope, South Africa, tichtzachitott, the reef chiton that lives today in the Philippines and northern Australia, had representatives in the Marshall Islands and Palau during the Miocene. Ties between the island area and the Americas are suggested, but they are less impressive t...

Hydrogeological support to United States military operations, 1917–2010

Over the past 100 years, hydrogeology has played a role in most military operations undertaken by the USA. The first significant application by US forces took place during World War I, on the Western Front. America's entry into World War II highlighted the need for military hydrogeologists once again, and a combination of civilian and uniformed hydrogeologists provided valuable support to the war effort, notably by terrain analysis. During the Cold War, the United States Geological Survey Military Geology Branch conducted military hydrogeological studies, and in 1985 the US Army Corps of Engineers created the Water Detection Response Team (WDRT) to provide hydrogeological expertise to military well-drilling units. During the Persian Gulf War of 1990–1991, groundwater was important for sustaining troops living in the northern Saudi Arabian desert. Operations in Bosnia and Kosovo later in that decade required the assistance of the WDRT in obtaining adequate groundwater supplies for base camps. Current military operations in Afghanistan rely on groundwater as a significant source for most US bases. In combination, uniformed and civilian geologists serving in a variety of roles to support American troops have located water supplies essential to the success of US military operations around the globe.
