Geologic setting of massive sulfide deposits and hydrothermal vents along the southern Juan de Fuca Ridge

This report incorporates data from two cruises of the USGS vessel SP LEE: (1) L12-80-WF from 29 October to 13 November 1980, and (2) L11-81-WF from 4 to 15 September 1981. The 1980 cruise occurred long after the optimum weather window for this region. The natural results was that no photographic or sample stations could be attempted during nearly continuous gale- and storm-force winds, which twice forced the vessel to depart the work area for safety. A detailed bathymetric survey of a 35-km seg… more

Littoral processes: US Coast Guard Station, Fort Point, San Francisco

The US Coast Guard Station, Fort Point is located three-quarters of a nautical mile southeast of the Golden Gate Strait, the entrance to San Francisco Bay. The existing storm wave conditions at Fort Point Station pier make it extremely dangerous for the SAR crews to get on and off the Motor Life Boats at times requiring the vessels to be moored at the San Francisco Yacht Harbor about 1.5 miles east of the Fort Point Station. To mitigate these harsh working conditions the US Coast Guard is consi… more

Use of a United States mid-Pacific Island territory for a Pacific Island Repository System (PIRS): Extended summary

The concept of using a mid-ocean island for a geologic high-level waste repository was investigated. The technical advantages include geographical isolation and near-infinite ocean dilution as a backup to repository geological waste isolation. The institutional advantages are reduced siting problems and the potential of creating an international waste repository. Establishment of international waste repository would allow cost sharing, aid US nonproliferation goals, and assure proper disposal o… more

Historical /sup 14/C measurement from the Atlantic, Pacific, and Indian Oceans. Progress report, December 1, 1978-August 31, 1979

Between the years 1964 and 1974, over 1000 sea water samples were collected from various locations and depths to 4000 M. These samples were processed to recover inorganic carbon (as CO/sub 2/) for laboratory measurement of /sup 14/C. Aliquots of sea water, poisoned with mercuric chloride, were collected at the same time for total CO/sub 2/ measurement. During laboratory workup approximately 1/2 of the samples had small aliquots of CO/sub 2/ set aside for /sup 13/C//sup 12/C isotope ratio measur… more

Where do fossil fuel carbon dioxide emissions from California go? An analysis based on radiocarbon observations and an atmospheric transport model

Characterizing flow patterns and mixing of fossil fuel-derived CO{sub 2} is important for effectively using atmospheric measurements to constrain emissions inventories. Here we used measurements and a model of atmospheric radiocarbon ({sup 14}C) to investigate the distribution and fluxes of atmospheric fossil fuel CO{sub 2} across the state of California. We sampled {sup 14}C in annual C{sub 3} grasses at 128 sites and used these measurements to test a regional model that simulated anthropogeni… more

The continental margin is a key source of iron to the HNLC North Pacific Ocean

Here we show that labile particulate iron and manganese concentrations in the upper 500m of the Western Subarctic Pacific, an iron-limited High Nutrient Low Chlorophyll (HNLC) region, have prominent subsurface maxima between 100-200 m, reaching 3 nM and 600 pM, respectively. The subsurface concentration maxima in particulate Fe are characterized by a more reduced oxidation state, suggesting a source from primary volcagenic minerals such as from the Kuril/Kamchatka margin. The systematics of the… more

FINAL FRONTIER AT HANFORD TACKLING THE CENTRAL PLATEAU

The large land area in the center of the vast Department of Energy (DOE) Hanford Site in southeast Washington State is known as 'the plateau'--aptly named because its surface elevations are 250-300 feet above the groundwater table. By contrast, areas on the 585-square mile Site that border the Columbia River sit just 30-80 feet above the water table. The Central Plateau, which covers an ellipse of approximately 70 square miles, contains Hanford's radiochemical reprocessing areas--the 200 East a… more

Final Technical Report: The Effects of Iron Complexing Ligands on the Long Term Ecosystem Response to Iron Enrichment of HNLC waters

Substantial increases in the concentrations of the stronger of two Fe(III) complexing organic ligand classes measured during the mesoscale Fe enrichment studies IronEx II and SOIREE appeared to sharply curtailed Fe availability to diatoms and thus limited the efficiency of carbon sequestration to the deep. Detailed observations during IronEx II (equatorial Pacific Ocean) and SOIREE (Southern Ocean –Pacific sector) indicate that the diatoms began re-experiencing Fe stress even though dissolved F… more

Application of Bomb Radiocarbon Chronologies to Shortfin Mako (Isurus oxyrinchus)

There is an ongoing disagreement regarding the aging of the shortfin mako due to a difference of interpretation in the periodic deposition of vertebral growth band pairs, especially for the larger size classes. Using analysis of length-month information, tagging data, and length-frequency analysis, concluded that two band pairs were formed in the vertebral centrum every year (biannual band-pair interpretation). Cailliet et al. (1983), however, presented growth parameters based on the common ass… more

Interseasonal air-sea interactions in the OSU (Oregon State University) coupled upper ocean-atmosphere GCM (general circulation model)

In this paper we examine the climatology of some variables which play an important role in the generation of low frequency variability in the Oregon State University coupled upper ocean-atmosphere general circulation model (GCM). The atmospheric model, representing the troposphere, consists of two equal mass layers between the surface and 200mb. The ocean model, developed by Pollard (1982), consists of two variable depth layers crudely representing the mixed layer and thermocline which overlie … more

Puget Sound area electric reliability plan

Various conservation, load management, and fuel switching programs were considered as ways to reduce or shift system peak load. These programs operate at the end-use level, such as residential water heat. Figure D-1a shows what electricity consumption for water heat looks like on normal and extreme peak days. Load management programs, such as water heat control, are designed to reduce electricity consumption at the time of system peak. On the coldest day in average winter, system load peaks nea… more

Blast induced subsidence in the craters of nuclear tests over coral

The craters from high-yield nuclear tests at the Pacific Proving Grounds are very broad and shallow in comparison with the bowl-shaped craters formed in continental rock at the Nevada Test Site and elsewhere. Attempts to account for the differences quantitatively have been generally unsatisfactory. We have for the first time successfully modeled the Koa Event, a representative coral-atoll test. On the basis of plausible assumptions about the geology and about the constitutive relations for cora… more
