Summary 1. Abstract This report describes submersible observations and collections made during an OE expedition along a transect centered on the Latitude 31º30’ line, in depths from 55 to 1000 m. The sampling extended from previous work along that transect (including some funded by OE and other NOAA offices) that sampled from the coast out to 55 m. This report describes observations of fishes made from submersible, description of habitats and bottom types, analysis of infaunal invertebrates collected by the submersible and a Young grab, analysis of the fauna inhabiting some sponges and tunicates, and analysis of isotope composition of coral samples to determine paleo- oceanographic conditions and coral growth rates. 2. Purpose of Project: a. Describe issue that was addressed The Blake Plateau and the Southeast Continental Slope: The Blake Plateau, a feature that dominates the continental margin off the southeastern U.S, interrupts the continental slope with a relatively gently sloping topography from 700 to 1100 m depth (Fig. 1). Much of the Blake is relatively flat hard bottom (Popenoe and Manheim 2001), but at the northern end lies an area of extremely rugged relief (the Charleston Bump) that has received attention because of its importance in Gulf Stream dynamics and fisheries (Sedberry et al. 2001; Govoni and Hare 2001; Sedberry et al. OE Bump final report). In spite of recent exploration of the Charleston Bump (Sedberry et al. 2005), relatively little is known about the deep continental slope of the southeastern U.S., relative to shelf habitats. The recent work on the Charleston Bump and adjacent Florida-Hatteras Slope has coincided with, or resulted from, development of deepwater fisheries for golden crabs (Geryonidae), groupers (Serranidae), wreckfish (Polyprionidae) ocean perches (Scorpaenidae), tilefishes (Malacanthidae), alfonsinos (Berycidae), roughies (Trachichthyidae), and other groups (Sedberry et al. 2001; Wenner and Barans 2001). Ecological studies aimed at understanding the assemblages that co-occur with fishery species, and which play roles in food chain dynamics and fish production, have been little studied. Studies of western Atlantic slope habitats north of Cape Hatteras and south of Cape Canaveral have found increased biomass and productivity between areas of topographic relief (canyons) relative to more tranquil open slope areas (Musick et al. 1975; Crabtree et al. 1991). Studies have also compared more productive soft bottom slope habitats of the Middle Atlantic Bight (Cape Cod to Cape Hatteras) with soft bottom habitats in deep waters * Blake Plateau Figure 1. Bottom topography (above) and areas of known hard bottom (right) on the Blake Plateau. The black rectangular boxes indicate the location of the 31-30 Transect, which passes over the rough bottom topography of the Charleston Bump (*). The figure at right, which covers the area of the red rectangle on the figure above, is from Manheim and Popenoe (2001). of the tropics, and have included community and trophic ecology comparisons from temperate and subtropical regions (Sedberry and Musick 1978; Anderson et al. 1986; Crabtree et al. 1991). Differences in species composition and trophic structure of fish communities, and morphology of the deep-sea fish faunas have been attributed to differing levels of nutrient and/or oxygen concentrations between demersal habitats of the two regions and other attributes associated with the presence of bottom topography such as canyons, seamounts, ridges and hard bottom (Sulak and Ross 1996). Although the Blake Plateau may serve as an important transition zone between tropical and temperate deep-sea faunas, it has been little studied because of the difficulty of sampling with traditional sampling gear. Hard Bottom Habitat and Regional Biogeography: The continental shelf off the southeastern U.S. is often referred to as the South Atlantic Bight (or SAB), which is defined herein as the continental shelf and slope between Cape Hatteras and Cape Canaveral and out to the edge of the Exclusive Economic Zone (or EEZ). Although hard bottom habitats, consisting of rock outcrops and living coral patches, occur scattered along the continental shelf of the SAB, little research effort has been directed at deep-water rocky habitats (Anonymous 1985). Hard bottom habitats on the continental shelf and upper slope of the SAB support drastically different fish faunas than do soft bottom habitats in similar depths and thermal regimes (Wenner 1983; Sedberry and Van Dolah 1984). It is likely that these differences extend to the deeper waters of the Florida-Hatteras Slope, Blake Plateau and beyond. Thus, deepwater rocky bottom habitats such as those found on the Blake Plateau (Fig. 1) may support greater biomass and diversity of fishes than that found on adjacent soft bottom areas. For this reason, demersal fisheries of the Blake concentrate on hard bottom areas. The hard bottom shelf of the SAB supports tropical and subtropical reef fishes. Many of these fishes are species that have extended their ranges northward from the Caribbean, taking advantage of rocky reef habitat and relatively stable thermal regimes of the SAB. It is unknown if the ichthyofauna associated with deep hard bottom of the Caribbean extends its range northward along the hard bottom habitat of the Blake Plateau. Similarly, the faunal affinities between the rocky bottom of the Blake Plateau and rocky North Atlantic islands such as Bermuda and the Azores is not known, although fishery landings [e.g. wreckfish (Polyprion americanus), blackbelly rosefish (Helicolenus dactylopterus), red porgy (Pagrus pagrus), etc.] indicate many similarities (Sedberry et al. 1999). "Islands" of suitable habitat, such as the Bahamas and Charleston Bump, may provide "stepping stones" to allow the distribution of deep, rocky-bottom fishes from the Caribbean to the eastern Atlantic. Faunal study of deep hard bottom habitats in the Caribbean, Blake Plateau and across the North Atlantic are needed to determine patterns of species distributions, dispersal and zoogeographic affinities. Recent studies have shown decreasing average size of species and individuals within species of deep-sea fishes from north to south along the middle continental slope (Sulak and Ross 1996). An obvious contradiction to this trend is found in the occurrence of concentrations of large species such as wreckfish, barrelfish (Hyperoglyphe perciformis) and red bream (Beryx decadactylus) on mid-slope depths on the Blake Plateau. Wreckfish have supported large fishery landings [in excess of 4 million lbs in 1990 until the South Atlantic Fishery Management Council (SAFMC) established catch restrictions (Sedberry et al. 1994). This high concentration of biomass on the Blake Plateau corresponds to the location of the high-relief bottom topography. It is unknown if deeper or less rugged hard bottom of the Blake Plateau east of the Bump also supports a high biomass of fishes and other organisms. Oceanography, Life History, Recruitment: The relationship between oceanography and fisheries production on the Blake Plateau is not well understood. An additional enigma is that the very currents that cause the upwellings that increase productivity (Bane et al. 2001) should carry away the pelagic eggs, larvae and juveniles of fishery species such as wreckfish that spawn on the Bump, leaving questions regarding the recruitment of fishes, corals and other species to the Blake Plateau. There may be downstream eddies that retain early life stages in a "nursery area" associated with the Bump, or recruitment to the area may come from upstream in the Caribbean. Successful recruitment of corals and other species may occur only in areas of reduced current flow. Fine-scale mapping of species’ distributions and hydrography over a variety of bottom types and depths is needed to determine factors affecting successful recruitment in fishes, corals and other organisms under the Gulf Stream on the Blake Plateau. Downstream from the Blake Plateau are several seamounts and archipelagos, including those associated with the mid-Atlantic ridge. The Azores islands and nearby banks provide hard bottom habitat within the axis of the Gulf Stream as it drifts toward northern Europe, and these shallow parts of the mid-Atlantic ridge support fisheries for species that also occur on the Blake Plateau.

  • Taxonomy and Diversity of the Sponge Fauna from Walters Shoal, a Shallow Seamount in the Western Indian Ocean Region
    Taxonomy and diversity of the sponge fauna from Walters Shoal, a shallow seamount in the Western Indian Ocean region By Robyn Pauline Payne A thesis submitted in partial fulfilment of the requirements for the degree of Magister Scientiae in the Department of Biodiversity and Conservation Biology, University of the Western Cape. Supervisors: Dr Toufiek Samaai Prof. Mark J. Gibbons Dr Wayne K. Florence The financial assistance of the National Research Foundation (NRF) towards this research is hereby acknowledged. Opinions expressed and conclusions arrived at, are those of the author and are not necessarily to be attributed to the NRF. December 2015 Taxonomy and diversity of the sponge fauna from Walters Shoal, a shallow seamount in the Western Indian Ocean region Robyn Pauline Payne Keywords Indian Ocean Seamount Walters Shoal Sponges Taxonomy Systematics Diversity Biogeography ii Abstract Taxonomy and diversity of the sponge fauna from Walters Shoal, a shallow seamount in the Western Indian Ocean region R. P. Payne MSc Thesis, Department of Biodiversity and Conservation Biology, University of the Western Cape. Seamounts are poorly understood ubiquitous undersea features, with less than 4% sampled for scientific purposes globally. Consequently, the fauna associated with seamounts in the Indian Ocean remains largely unknown, with less than 300 species recorded. One such feature within this region is Walters Shoal, a shallow seamount located on the South Madagascar Ridge, which is situated approximately 400 nautical miles south of Madagascar and 600 nautical miles east of South Africa. Even though it penetrates the euphotic zone (summit is 15 m below the sea surface) and is protected by the Southern Indian Ocean Deep- Sea Fishers Association, there is a paucity of biodiversity and oceanographic data.

Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described.

  • From the Southeast Australian Coast, with Comments on the Distribution and Habitat Preferences of Chondropodinae
    Muvi schmallenbergi gen. nov., sp. nov. (Crustacea, Tanaidacea) from the southeast Australian coast, with comments on the distribution and habitat preferences of Chondropodinae Piotr Jóźwiak and Magdalena Błażewicz Department of Invertebrate Zoology and Hydrobiology, Faculty of Biology and Environmental Protection, University of Łódź, Łódź, Poland ABSTRACT Based on material collected from the shelf off southeast Australia (offshore of Portland), a new genus and new species, Muvi schmallenbergi gen. nov., sp. nov., of the tanaidacean family Metapseudidae, is described. Muvi is distinguishable from other genera within the subfamily Chondropodinae by having equally long antennular flagella. It also differs from other Chondropodinae by a combination of characters such as eyelobes with a group of visual elements, rostrum with smooth lateral edges, pereonites with lateral processes and pleotelson lacking lateral process, antennule article-1 with a single apophysis, maxillule inner lobe well-developed, labial palp bearing three distal setae, cheliped exopod well-developed and setose, pereopod-1 coxa with distinct apophysis, pleopods in five pairs, and uropod basis without apophysis. The genus Deidamiapseudes Sganga & Roccatagliata, 2016 is moved from Chondropodinae (Metapseudidae) to Apseudoidea incertae sedis. An identification key for the genera within Chondropodinae is given, and their distribution is discussed.

  • Proposal for a Revised Classification of the Demospongiae (Porifera) Christine Morrow1 and Paco Cárdenas2,3*
    Morrow and Cárdenas Frontiers in Zoology (2015) 12:7 DOI 10.1186/s12983-015-0099-8 DEBATE Open Access Proposal for a revised classification of the Demospongiae (Porifera) Christine Morrow1 and Paco Cárdenas2,3* Abstract Background: Demospongiae is the largest sponge class including 81% of all living sponges with nearly 7,000 species worldwide. Systema Porifera (2002) was the result of a large international collaboration to update the Demospongiae higher taxa classification, essentially based on morphological data. Since then, an increasing number of molecular phylogenetic studies have considerably shaken this taxonomic framework, with numerous polyphyletic groups revealed or confirmed and new clades discovered. And yet, despite a few taxonomical changes, the overall framework of the Systema Porifera classification still stands and is used as it is by the scientific community. This has led to a widening phylogeny/classification gap which creates biases and inconsistencies for the many end-users of this classification and ultimately impedes our understanding of today’s marine ecosystems and evolutionary processes. In an attempt to bridge this phylogeny/classification gap, we propose to officially revise the higher taxa Demospongiae classification. Discussion: We propose a revision of the Demospongiae higher taxa classification, essentially based on molecular data of the last ten years. We recommend the use of three subclasses: Verongimorpha, Keratosa and Heteroscleromorpha. We retain seven (Agelasida, Chondrosiida, Dendroceratida, Dictyoceratida, Haplosclerida, Poecilosclerida, Verongiida) of the 13 orders from Systema Porifera. We recommend the abandonment of five order names (Hadromerida, Halichondrida, Halisarcida, lithistids, Verticillitida) and resurrect or upgrade six order names (Axinellida, Merliida, Spongillida, Sphaerocladina, Suberitida, Tetractinellida). Finally, we create seven new orders (Bubarida, Desmacellida, Polymastiida, Scopalinida, Clionaida, Tethyida, Trachycladida).

Initially it was found only in Corio Bay, but during the past fiveyears it has spread so that it now occurs throughout the western half of Port Phillip Bay. • Densities of Sabella in many parts of the bay remain low but densities are usually higher (up to 13/m2 ) in deeper water and they extend into shallower depths in calmer regions. • Sabella larvae probably require a 'hard' surface (shell fragment, rock, seaweed, mollusc or sea squirt) for initial attachment, but subsequently they may use their own tube as an anchor in soft sediment . • Changes to fish communities following the establishment of Sabella were analysed using multidimensional scaling and BACI (Before, After, Control, Impact) design analyses of variance.

On the origin and evolution of Antarctic Peracarida (Crustacea, Malacostraca)* ANGELIKA BRANDT Zoological Institute and Zoological Museum, Martin-Luther-King-Platz 3, D-20146 Hamburg, Germany Dedicated to Jürgen Sieg, who silently died in 1996. He inspired this research with his important account of the zoogeography of the Antarctic Tanaidacea. SUMMARY: The early separation of Gondwana and the subsequent isolation of Antarctica caused a long evolutionary his- tory of its fauna. Both, long environmental stability over millions of years and habitat heterogeneity, due to an abundance of sessile suspension feeders on the continental shelf, favoured evolutionary processes of “preadapted“ taxa, like for exam- ple the Peracarida. This taxon performs brood protection and this might be one of the most important reasons why it is very successful (i.e. abundant and diverse) in most terrestrial and aquatic environments, with some species even occupying deserts. The extinction of many decapod crustaceans in the Cenozoic might have allowed the Peracarida to find and use free ecological niches. Therefore the palaeogeographic, palaeoclimatologic, and palaeo-hydrographic changes since the Palaeocene (at least since about 60 Ma ago) and the evolutionary success of some peracarid taxa (e.g. Amphipoda, Isopo- da) led to the evolution of many endemic species in the Antarctic. Based on a phylogenetic analysis of the Antarctic Tanaidacea, Sieg (1988) demonstrated that the tanaid fauna of the Antarctic is mainly represented by phylogenetically younger taxa, and data from other crustacean taxa led Sieg (1988) to conclude that the recent Antarctic crustacean fauna must be comparatively young.

Yet they have no obligate dispersive phase in their life-cycle. Populations are thus inevitably isolated, and allopatric speciation and high regional diversity are inevitable; cosmopolitan distributions are considered to be unlikely or non-existent.
