Gamma Ray Spectrometry ACKNOWLEDGMENTS A major expense in oceanographic research is "time at sea." Operations on the* R/V YAQUINA, our primary vessel, were funded by several agencies, with the bulk of the support coming from the National Science Foundation and the Office of Naval Research.Certain special cruises of radiochemical or radioecological import were funded by the Atomic Energy Commission, as was much of the equipment for radio-analysis and stable element analysis. Most of the support for student research, plus some of the gamma spectrometry facilities, were provided by the U. S. Public Health Service.We gratefully acknowledge the role of these agencies in support of the research reported in the following pages.

C’est tout d’abord grâce au programme vERSO (Ecosystem Responses to global change : a multiscale approach in the Southern Ocean) que ce travail a été possible, mais aussi grâce aux collaborations construites avant et pendant ce travail. Cette thèse a aussi été l’occasion de continuer à aller travailler sur le terrain des hautes latitudes à plusieurs reprises pour collecter les échantillons et rencontrer de nouveaux collègues. Par le biais de ces trois missions de recherches et des nombreuses conférences auxquelles j’ai activement participé à travers le monde, j’ai beaucoup appris, tant scientifiquement qu’humainement.

Wilson1, J. Zhang3,15 and N. J. Bax2,16 Abstract Background: Our knowledge of the benthic fauna at lower bathyal to abyssal (LBA, > 2000 m) depths off Eastern Australia was very limited with only a few samples having been collected from these habitats over the last 150 years. In May–June 2017, the IN2017_V03 expedition of the RV Investigator sampled LBA benthic communities along the lower slope and abyss of Australia’s eastern margin from off mid-Tasmania (42°S) to the Coral Sea (23°S), with particular emphasis on describing and analysing patterns of biodiversity that occur within a newly declared network of offshore marine parks. Methods: The study design was to deploy a 4 m (metal) beam trawl and Brenke sled to collect samples on soft sediment substrata at the target seafloor depths of 2500 and 4000 m at every 1.5 degrees of latitude along the western boundary of the Tasman Sea from 42° to 23°S, traversing seven Australian Marine Parks.

Cottreaucorys kollmanni n.sp. is established for a new small aeropsid, a group of rare deep-water spatangoids. Furthermore, the species Procassidulus cf. elongatus and Galeaster bertrandi are recorded for the first time from Austria.

Nielsena,*, Daniel Frassinettib, Klaus Bandela aGeologisch-Pala¨ontologisches Institut und Museum, Universita¨t Hamburg, Bundesstrasse 55, 20146 Hamburg, Germany bMuseo Nacional de Historia Natural, Casilla 787, Santiago, Chile Abstract Species of Vetigastropoda (Fissurellidae, Turbinidae, Trochidae) and one species of Neritimorpha (Neritidae) from the Navidad area, south of Valparaı´so, and the Arauco Peninsula, south of Concepcio´n, are described. Among these, the Fissurellidae comprise Diodora fragilis n. sp., Diodora pupuyana n. sp., two additional unnamed species of Diodora, and a species resembling Fissurellidea. Turbinidae are represented by Cantrainea sp., and Trochidae include Tegula (Chlorostoma) austropacifica n. sp., Tegula (Chlorostoma) chilena n. sp., Tegula (Chlorostoma) matanzensis n. sp., Tegula (Agathistoma) antiqua n. sp., Bathybembix mcleani n. sp., Gibbula poeppigii [Philippi, 1887] n. comb., Diloma miocenica n. sp., Fagnastesia venefica [Philippi, 1887] n. gen. n. comb., Fagnastesia matanzana n. gen. n. sp., Calliostoma mapucherum n. sp., Calliostoma kleppi n. sp., Calliostoma covacevichi n. sp., Astele laevis [Sowerby, 1846] n. comb., and Monilea riorapelensis n. sp. The Neritidae are represented by Nerita (Heminerita) chilensis [Philippi, 1887]. The new genus Fagnastesia is introduced to represent low-spired trochoideans with a sculpture of nodes below the suture, angulated whorls, and a wide umbilicus. This Miocene Chilean fauna includes genera that have lived at the coast and in shallow, relatively warm water or deeper, much cooler water. This composition therefore suggests that many of the Miocene formations along the central Chilean coast consist of displaced sediments.

  • Big Oyster, Robust Echinoid: an Unusual Association from the Maastrichtian Type Area (Province of Limburg, Southern Netherlands)
    Swiss Journal of Palaeontology (2018) 137:357–361 https://doi.org/10.1007/s13358-018-0151-3 (0123456789().,-volV)(0123456789().,-volV) REGULAR RESEARCH ARTICLE Big oyster, robust echinoid: an unusual association from the Maastrichtian type area (province of Limburg, southern Netherlands) 1,2 3 Stephen K. Donovan • John W. M. Jagt Received: 27 February 2018 / Accepted: 10 May 2018 / Published online: 1 June 2018 Ó Akademie der Naturwissenschaften Schweiz (SCNAT) 2018 Abstract Large, denuded tests of holasteroid echinoids were robust benthic islands in the Late Cretaceous seas of northwest Europe. A test of Hemipneustes striatoradiatus (Leske) from the Nekum Member (Maastricht Formation; upper Maastrichtian) of southern Limburg, the Netherlands, is encrusted by a large oyster, Pycnodonte (Phygraea) vesiculare (Lamarck). This specimen is a palaeoecological conundrum, at least in part. No other members of the same oyster spatfall attached to this test and survived. Indeed, only two other, much smaller bivalve shells, assignable to the same species, attached either then or somewhat later. The oyster, although large, could have grown to this size in a single season. The larval oyster cemented high on the test and this would have been advantageous initially, the young shell being elevated above sediment-laden bottom waters. However, as the oyster grew, the incurrent margin of the commissure would have grown closer to the sediment surface. Thus, the quality of the incurrent water probably deteriorated with time.
