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. -
Mollusca, Pholadidae, Xylophagainae)
Turner: Xylopholas altenai 97 n. gen. n. sp. A new genus and species of deep water wood-boring bivalve (Mollusca, Pholadidae, Xylophagainae) by Ruth+D. Turner Museum ofComparativeZoology, Harvard University, Cambridge,Mass., U.S.A. The Xylophagainae are marine wood-boring bivalves which are confined than 150 largely to depths greater meters. They are not found the intertidal the sublittoral in zone, occur in only in higher latitudes, and are the sole wood-borers in depths over 200 meters. The greatest known depth for the invasion oftest wood by Teredini- dae is 200 meters (Tipper, 1968). The known depth range for the Xylophagainae extends from two meters below low tide in Millport, Scotland, to 7290 meters in the Banda Trench, off Ceram. Only occasionally are they found in drift wood, and this is usually after storms, the water logged wood having been lifted offthe bottom and carried ashore by strong waves. The discovery of the new genus and species described here is the result of a world-wide study of the Xylophagainae, a subfamily of the Pholadidae characterized by teredinid-like shells and a small, divided mesoplax. They lack apophyses (as do the Jouannetiinae) and do not produce a callum in the adult stage (as in the Phola- in dinae). They are unique among the Pholadidae having a wood- storing caecum. The author is grateful to Dr. Frederick Bayer, Rosenstiel School of Marine and Atmospheric Sciences, University of Miami, Dr. J0r- gen Knudsen, Universitetets Zoologiske Museum, Copenhagen, Den- mark, and Dr. W. Adam, Institut Royal des Sciences Naturelles de Belgique, Brussels, Belgium, for the loan of specimens and the opportunity to remove specimens from dredged wood or other plant material in their collections. -

A Preliminary Report on Expeditions Monsoon And
A Preliminary Report on Expeditions Monsoon and Lusiad 1960 - 1963 University of California, San Diego Scripps Institution of Oceanography Cruises to the Indian Ocean By The Members of the Expedition Edited by Robert L. Fisher S. I. O. Reference 64-19 ― i ― FOREWORD Field participation in the International Indian Ocean Expedition by scientists and research vessels of the University of California's Scripps Institution of Oceanography comprises three multi- program investigations: MONSOON (1960-1), LUSIAD (1962-3) and DODO (1964). All three expeditions, though first broadly outlined in 1959, lie within the cooperative international exploration of the Indian Ocean being sponsored by the Scientific Committee on Oceanic Research and UNESCO. Therefore, though original schedules have to date been met, the programs have in fact been influenced and modified by the plans, interests and findings of other agencies and laboratories, and direct participation by marine scientists, students and trainees from other areas has been welcomed. Although the final SIO IIOE cruise, DODO, is just underway, a preliminary report on some generalized results of the first two expeditions seems appropriate now, with the clear understanding that many conclusions stated here may indeed be premature. Final analyses, syntheses and results will appear in more specialized formal publications and in the proposed SCOR-sponsored atlases which eventually will summarize Indian Ocean Expedition findings. At Scripps Institution, it is customary to give names, rather than number designations, to the major expeditions. The 1960-1 investigation, 3 ½ months in the Indian Ocean, embraced the first SIO field work in the "monsoon seas". It was funded primarily by the Office of Naval Research of the Navy Department, with auxiliary support for personnel and special equipment from the Bureau of Ships and the National Science Foundation. -

Deep-Sea Life Issue 16, January 2021 Cruise News Sedimentation Effects Survey Series (ROBES III) Completed
Deep-Sea Life Issue 16, January 2021 Despite the calamity caused by the global pandemic, we are pleased to report that our deep ocean continues to be investigated at an impressive rate. Deep-Sea Life 16 is another bumper issue, brimming with newly published research, project news, cruise news, scientist profiles and so on. Even though DOSI produce a weekly Deep-Sea Round Up newsletter and DOSI and DSBS are active on social media, there’s still plenty of breaking news for Deep- Sea Life! Firstly a quick update on the status of INDEEP. As most of you are aware, INDEEP was a legacy programme of the Census of Marine Life (2000-2010) and was established to address knowledge gaps in deep-sea ecology. Among other things, the INDEEP project played central role in the creation of the Deep-Ocean Stewardship Initiative and funded initial DOSI activities. In 2018, the DOSI Decade of Ocean Science working group was established with a view to identifying key priorities for deep-ocean science to support sustainable development and to ensure deep- ocean ecological studies were included in the UN Decade plans via truly global collaborative science. This has resulted in an exciting new initiative called “Challenger 150”. You are all invited to learn more about this during a webinar on 9th Feb (see p. 22 ). INDEEP has passed on the baton and has now officially closed its doors.Eva and I want to sincerely thank all those that led INDEEP with us and engaged in any of the many INDEEP actions. It was a productive programme that has left a strong legacy. -
Morphological Description of Cyrtopleura Costata (Bivalvia: Pholadidae) from Southern Brazil

ORCID: http://orcid.org/0000-0002-1397-9823. E-mail: [email protected] Abstract. The aim of the study is to describe in detail, for the first time, the internal and external anatomy of Cyrtopleura costata, which displays ellipsoid and elongated valves with beige periostracum, the anterior adductor muscle unites the valves in the pre- umbonal region, with abduction capacity in its dorsal half, sparing the ligament. Two accessory valves are identified: the mesoplax (calcified) located in the umbonal region; and the protoplax (corneus) above the anterior adductor muscle. Internally there is a pair of well-developed apophysis that supports the labial palps and the pedal muscles, and support part of the gills. The posterior half of mantle ventral edge is fused and richly muscular, working as auxiliary adductor muscle. The siphons are completely united with each other, the incurrent being larger than the excurrent. The foot is small (about ⅛ the size of the animal). The kidneys extend laterally on the dorsal surface, solid, presenting a brown/reddish color. The style sac is well developed and entirely detached from the adjacent intestine. The intestine has numerous loops and curves within the visceral mass. The fecal pellets are coin-shaped. -
Morphological and Genetic Diversity of the Wood-Boring Xylophaga (Mollusca, Bivalvia): New Species and Records from Deep-Sea Iberian Canyons
Morphological and Genetic Diversity of the Wood-Boring Xylophaga (Mollusca, Bivalvia): New Species and Records from Deep-Sea Iberian Canyons Chiara Romano1*, Janet Ruth Voight2, Rocı´oPe´ rez-Portela1, Daniel Martin1 1 Centre d’Estudis Avancats de Blanes (CEAB - CSIC), Blanes (Girona), Catalunya, Spain, 2 Integrative Research Center, The Field Museum, Chicago, Illinois, United States of America Abstract Deep-sea bivalves of the Xylophagaidae, a poorly known group, are obligate wood-borers. Deployment of wood in three submarine canyons off the Iberian coast, the Blanes and La Fonera Canyons (Mediterranean Sea) and the Avile´s Canyon (Cantabric Sea, Bay of Biscay), lead to the discovery of four xylophagaid species in our samples. Xylophaga dorsalis (the dominant species), X. atlantica, X. cf. anselli and the new species X. brava, were identified on the basis of morphological data, and supported by a phylogenetic reconstruction based on the nuclear genes 18S rDNA and 28S rDNA and including several genus of Xylophagaidae. Genetic divergence between species of Xylophaga varied between genes, ranging from 0.5 to 4.0% for the 18SrDNA and from 4.1 to 16.6% for the 28SrDNA. Xylophaga brava sp. nov. appeared to be restricted to the Mediterranean and morphologically resembled the closely related X. cf. anselli from the Cantabrian Sea. However, they clearly diverged in two well-supported clades. Low levels of intraspecific variability and higher interspecific divergence between species also supported the existence of these two different species. Morphologically they differ in the number of cirri at the siphon openings, in the shape of the posterior shell and in the size of prodissoconch II. -
