Retrotapes andrillorum n. sp., Hiatella cf. arctica (Linnaeus, 1767), ?Yoldia
sp. (internal mould), and six taxa of Pectinidae are reported from the Burdigalian
section of the ANDRILL 2A core, drilled in McMurdo Sound, Ross Sea. The pectinids
are Adamussium cf. jonkersi Quaglio et al., 2010, Antarctipecten n. gen. alanbeui
(Jonkers, 2003), Austrochlamys forticosta n. sp., Austrochlamys cf. marisrossensis
Jonkers, 2003, Ruthipecten n. gen., n. sp. (not named), and a fragmentary specimen
representing an unnamed genus and species. In a revision of Antarctic Pectinidae,
Austrochlamys Jonkers, 2003, Ruthipecten n. gen. (proposed for Chlamys
(Zygochlamys) tuftsensis Turner, 1967, reported only from Wright Valley and the
Vestfold Hills, not present in ANDRILL 2A), Leoclunipecten n. gen. (proposed for
Austrochlamys gazdzickii Jonkers, 2003, reported only from Oligocene rocks of King
George Island, not present in ANDRILL 2A) and the unnamed genus in ANDRILL 2A
are assigned to subfamily Chlamydinae, tribe Chlamydini, whereas Adamussium
Thiele, 1934 and Antarctipecten n. gen. are assigned to subfamily Palliolinae, tribe
Adamussiini. The diverse Pectinidae in ANDRILL 2A suggest sea temperatures
roughly 5°C warmer than at present in the Ross Sea during Early Miocene time.

Ciliate diversity, community structure, and novel taxa in lakes of the McMurdo Dry Valleys, Antarctica
Xu, Yuan; Vick-Majors, Trista; Morgan-Kiss, Rachael; Priscu, John C.; Amaral-Zettler, Linda A. (Marine Biological Laboratory, 2014-10-01)We report an in-depth survey of next-generation DNA sequencing of ciliate diversity and community structure in two permanently ice-covered McMurdo Dry Valley lakes during the austral summer and autumn (November 2007 and ... -
Airborne-radar and ice-core observations of annual snow accumulation over Thwaites Glacier, West Antarctica confirm the spatiotemporal variability of global and regional atmospheric models
Medley, Brooke; Joughin, Ian; Das, Sarah B.; Steig, Eric J.; Conway, Howard; Gogineni, S.; Criscitiello, Alison S.; McConnell, Joseph R.; Smith, B. E.; van den Broeke, Michiel R.; Lenaerts, Jan T. M.; Bromwich, D. H.; Nicolas, J. P. (John Wiley & Sons, 2013-07-26)We use an airborne-radar method, verified with ice-core accumulation records, to determine the spatiotemporal variations of snow accumulation over Thwaites Glacier, West Antarctica between 1980 and 2009. We also present a ... -
Climate forcing for dynamics of dissolved inorganic nutrients at Palmer Station, Antarctica : an interdecadal (1993–2013) analysis
Kim, Hyewon; Doney, Scott C.; Iannuzzi, Richard A.; Meredith, Michael P.; Martinson, Douglas G.; Ducklow, Hugh W. (John Wiley & Sons, 2016-09-17)We analyzed 20 years (1993–2013) of observations of dissolved inorganic macronutrients (nitrate, N; phosphate, P; and silicate, Si) and chlorophyll a (Chl) at Palmer Station, Antarctica (64.8°S, 64.1°W) to elucidate how ...
