Comparison of submersible-survey and hydroacoustic-survey estimates of fish density on a rocky bank

Creator:: Starr, Richard M., Fox, David S., Hixon, Mark Anthony, Tissot, Brian N., Johnson, Gary E., and Barss, William H.
Abstract:: Submersible belt-transect surveys along a rocky bottom were combined with acoustic surveys of the water column to estimate depth distribution and density of fishes at Stonewall Bank, Oregon in the northeastern Pacific Ocean from September through October 1991. The objectives of the study were to determine the proportion of fish...

Fish-habitat associations on a deep reef at the edge of the Oregon continental shelf

Creator:: Tissot, Brian N., Hixon, Mark Anthony, Barss, William, and Stein, David L.
Abstract:: Heceta Bank is a large reef on the edge of the central Oregon continental shelf that supports a wide variety of commercial fisheries. Using the research submersible Delta, we studied fish abundances on Heceta Bank and the relationship between species composition of fish assemblages and bottom types. Cluster analysis indicated...

Data report : major-element chemistry of Hole 896a glass

Creator:: Fisk, Martin R., McNeill, Andrew W., Teagle, Damon A. H., Furnes, Harald, and Bach, Wolfgang
Abstract:: Ocean Drilling Program Hole 896A (1°13.01'N, 83°43.39'W) is in 3440 m of water east of the Galapagos Platform in the equatorial eastern Pacific Ocean. At this site in 5.9 Ma crust, basement rocks were recovered over the depth range of 195.1 meters below seafloor (mbsf) to 469 mbsf. These rocks...

Data report : spectral reflectance observations from recovered sediments

Creator:: Ortiz, Joseph D., O'Connell, Suzanne, and Mix, Alan C.
Abstract:: Sediment spectral reflectance measurements were generated aboard the JOIDES Resolution during Ocean Drilling Program Leg 162 shipboard operations. The large size of the raw data set (over 1.3 gigabytes) and limited computer hard disk storage space precluded detailed analysis of the data at sea, although broad band averages were used...

Error in predicting hydrosol backscattering from remotely sensed reflectance

Creator:: Weidemann, A. D., Stavn, R. H., Zaneveld, J. Ronald, and Wilcox, M. R.
Abstract:: Monte Carlo simulations are carried out to determine the error in the inversion of backscattering from remotely sensed reflectance when geometrical shape factors of the light field are assumed to be unity. The results show that error in backscattering inversion can vary from a 40% overestimation to a 20% underestimation...

Crustal fissuring and its relationship to magmatic and hydrothermal processes on the East Pacific Rise crest (9°12′ to 54′N)

Creator:: Wright, Dawn J., Haymon, Rachel M., and Fornari, Daniel J.
Abstract:: The deep-towed Argo I optical/acoustical vehicle and a geographic information system (GIS) have been used to establish the abundance, widths, and spatial distribution of fissures, as well as the relative age distribution of lavas along the narrow (<500 m wide) axial zone of the East Pacific Rise (EPR) from 9°12′...

Foraminiferal faunal estimates of paleotemperature: Circumventing the no-analog problem yields cool ice age tropics

Creator:: Mix, Alan C., Morey, Ann E., Pisias, Nicklas G., and Hostetler, Steven W.
Abstract:: The sensitivity of the tropics to climate change, particularly the amplitude of glacial‐to‐interglacial changes in sea surface temperature (SST), is one of the great controversies in paleoclimatology. Here we reassess faunal estimates of ice age SSTs, focusing on the problem of no‐analog planktonic foraminiferal assemblages in the equatorial oceans that...

Microscale Quantification of the Absorption by Dissolved and Particulate Material in Coastal Waters with an ac-9

Creator:: Twardowski, Michael S., Sullivan, James M., Donaghay, Percy L., and Zaneveld, J. Ronald V.
Abstract:: Measuring coastal and oceanic absorption coefficients of dissolved and particulate matter in the visible domain usually requires a methodology for amplifying the natural signal because conventional spectrophotometers lack the necessary sensitivity. The WET Labs ac-9 is a recently developed in situ absorption and attenuation meter with a precision better than...

DC-8-based observations of aircraft CO, CH₄, N₂O, H₂O(G) emission indices during SUCCESS

Abstract:: We report the first measurements of CO₂, CH₄, N₂O, CO₂, and H₂O(g) in the exhaust trails of T-39, B-757, and DC-8 aircraft at cruise conditions. Emission indices (El) derived from these in-situ measurements are presented. Results are in agreement with ground-based tests indicating aircraft act as a net sink for...

Abstract:: A Russian–American fieldwork effort on Lake Baikal, its tributaries, and surrounding hot springs was undertaken in June–July 1991. Here we report on aspects of major ion (Ca2+, Mg2+, Na+, K+, Alk, Cl–, SO42–) and several minor and trace element (Li isotopes, Sr isotopes, Ba, Al, V, Cr, Ni, Cu, Ge,...
