    Benthic fauna of the Gulf of Maine sampled by R/V Gosnold Cruise 179 and DSRV Alvin Dives 329, 330, 331, and 404 : infaunal species list
    (Woods Hole Oceanographic Institution, 1975-07) Rowe, Gilbert T. ; Polloni, Pamela T. ; Haedrich, Richard L.
    Bottom samples were collected in the Gulf of Maine during July, 1971 and June, 1972 using DSRV ALVIN and RV GOSNOLD. The techniques and results are embodied in a paper entitled "Quantitative Biological Assessment of the Benthic Fauna in the Deep Basins of the Gulf of Maine" by G. T. Rowe, P. T. Polloni and R. L. Haedrich. Many of the conclusions made in that paper were based on summaries of the abundance of each benthic species of living invertebrate animal in each kind of sample, but those original data would not be accepted by the journal (JOURNAL OF THE FISHERIES RESEARCH BOARD OF CANADA) because the table was too long. The purpose of this technical report is to put those raw data in a form available(on request from the authors)to any interested ecologists.

    Bathymetric zonation of deep-sea macrofauna in relation to export of surface phytoplankton production
    (Inter-Research, 2010-01-28) Wei, Chih-Lin ; Rowe, Gilbert T. ; Hubbard, G. Fain ; Scheltema, Amelie H. ; Wilson, George D. F. ; Petrescu, Iorgu ; Foster, John M. ; Wicksten, Mary K. ; Chen, Min ; Davenport, Roe ; Soliman, Yousria ; Wang, Yuning
    Macrobenthos of the deep, northern Gulf of Mexico (GoM) was sampled with box cores (0.2 m2) along multiple cross-depth transects extending from depths of 200 m to the maximum depth of the basin at 3700 m. Bathymetric (depth) zonation of the macrofaunal community was documented for 6 major taxa (a total of 957 species) on the basis of shared species among geographic locations; 4 major depth zones were identified, with the 2 intermediate-depth zones being divided into east and west subzones. Change of faunal composition with depth reflects an underlying continuum of species replacements without distinct boundaries. The zonal patterns correlated with depth and detrital particulate organic carbon (POC) export flux estimated from remotely-sensed phytoplankton pigment concentrations in the surface water. The Mississippi River and its associated mesoscale eddies, submarine canyon, and deep sediment fan appear to influence the horizontal zonation pattern through export of organic carbon from the ocean surface and the adjacent continental margin. On the local scale, near-bottom currents may shape the zonation pattern by altering sediment grain size, food availability, and larval dispersal. This study suggests a macroecological relationship between depth, export POC flux, and zonation; parsimonious zonal thresholds need to be tested independently for other continental margin ecosystems.

    Sediment data from short cores taken in the northwest Atlantic Ocean
    (Woods Hole Oceanographic Institution, 2018-05) Rowe, Gilbert T. ; Clifford, C. Hovey
    This report presents data obtained from cored sediments collected during numerous cruises in the Northwest Atlantic area. The cores were obtained by SCUBA, gravity cores and DSRV ALVIN. The sediments were sampled with 6 centimeter diameter plastic core liners and ranged in length from 9 to 63 centimeters. Analyses conducted on sediment material include organic carbon, organic nitrogen, percent sand-silt-clay, percent calcium carbonate and pore water concentrations of ammonia, nitrite, nitrate, silicate and phosphate.
