Evidence for elevated alkalinity in the glacial Southern Ocean by Rickaby, R, Elderfield, H, Roberts, N, Hillenbrand, C, Mackensen, A

“…We present evidence, based on downcore measurements of benthic foraminiferal B/Ca and Mg/Ca from a core in the Weddell Sea, that the deep ocean carbonate ion concentration, [CO²⁻₃], was elevated by ~25 μmol/kg during each glacial period of the last 800 kyr. …”

Evidence for elevated alkalinity in the glacial Southern Ocean by Rickaby, R, Elderfield, H, Roberts, N, Hillenbrand, C, Mackensen, A

“…We present evidence, based on downcore measurements of benthic foraminiferal B/Ca and Mg/Ca from a core in the Weddell Sea, that the deep ocean carbonate ion concentration, [CO32-], was elevated by ∼25 μmol/ kg during each glacial period of the last 800 kyr. …”

Population genetics of the Antarctic heteronemertean Parbolasia corrugatus from the South Orkney Islands by Rogers, A, Clarke, A, Peck, L

“…It is hypothesised that recruitment of P. corrugatus in the South Orkney Islands originates from genetically distinct populations located in the Weddell Sea and to the west of the Antarctic Peninsula. …”

Early Last Interglacial ocean warming drove substantial ice mass loss from Antarctica by Turney, CSM, Fogwill, CJ, Golledge, NR, McKay, NP, van Sebille, E, Jones, RT, Etheridge, D, Rubino, M, Thornton, DP, Davies, SM, Ramsey, CB, Thomas, ZA, Bird, MI, Munksgaard, NC, Kohno, M, Woodward, J, Winter, K, Weyrich, LS, Rootes, CM, Millman, H, Albert, PG, Rivera, A, van Ommen, T, Curran, M, Moy, A, Rahmstorf, S, Kawamura, K, Hillenbrand, C-D, Weber, ME, Manning, CJ, Young, J, Cooper, A

“…Here, we report a blue-ice record of ice sheet and environmental change from the Weddell Sea Embayment at the periphery of the marine-based West Antarctic Ice Sheet (WAIS), which is underlain by major methane hydrate reserves. …”

Cadmium and phosphate in coastal Antarctic seawater: implications for Southern Ocean nutrient cycling by Hendry, K, Rickaby, R, de Hoog, J, Weston, K, Rehkämper, M

“…This implies that the Cd/PO₄³⁻ ratio of the Southern Ocean will vary on glacial-interglacial timescales as the proportion of deep water originating on the continental shelves of the Weddell Sea is reduced during glaciations because the ice shelf is pinned at the edge of the continental shelf. …”

Cadmium and phosphate in coastal Antarctic seawater: Implications for Southern Ocean nutrient cycling by Hendry, K, Rickaby, R, de Hoog, J, Weston, K, Rehkamper, M

“…This implies that the Cd/PO43- ratio of the Southern Ocean will vary on glacial-interglacial timescales as the proportion of deep water originating on the continental shelves of the Weddell Sea is reduced during glaciations because the ice shelf is pinned at the edge of the continental shelf. …”

Global distribution of the Th-230 flux to ocean sediments constrained by GCM modelling by Henderson, G, Heinze, C, Anderson, R, Winguth, A

“…An exception to this is the Weddell Sea, where the model has too little ice cover and too much lateral mixing, which prevents it from duplicating the observed high 230Th values. …”
