Macintyre, and Klaus Rützler, editors. Proceedings of the Smithsonian Marine Science Symposium. Smithsonian Contributions to the Marine Sciences, number 38, 529 pages, 217 figures, 47 tables, 2009.— The Smithsonian Marine Science Symposium was held on 15–16 November 2007 in Washington, D.C. It represented the first major dissemination of marine research results since the establishment of the Smithsonian Marine Science Network (MSN). The 39 papers in this volume represent a wide range of marine research studies that demonstrate the breadth and diversity of science initiatives supported by the MSN. The first section contains an overview of the MSN along with papers describing the multidisciplinary investigations spanning more than 37 years for the four Smithsonian marine facilities that constitute the Network: the Smithsonian Environmental Research Center at the Chesapeake Bay, Maryland; the National Museum of Natural History’s Smithsonian Marine Station at Fort Pierce, Florida; the Caribbean Coral Reef Ecosystems Program, with its Carrie Bow Marine Field Station in Belize; and the Smithsonian Tropical Research Institute in Panama. Subsequent papers represent findings by Smithsonian scholars and their collaborators on overarching topics of marine biodiversity, evolution, and speciation; biogeography, invasive species, and marine conservation; and forces of ecological change in marine systems.

Abstract: A computer file of all published distributional data (presence or absence) on the living and dead recent benthic foraminifera off the North American Pacific Coast (Oregon to Alaska) was constructed from 31 papers published since 1886. Manipulation of this file produced 5 catalogs and 139 maps. Catalog 1 lists alphabetically species names with publication and locality information as recorded in the literature (i.e., unsynonymized). Catalog 2 lists synonymized species names with publication and locality information. Catalogs 3 and 4 list alphabetically all unsynonymized and synonymized species names, respectively. Catalog 5 lists synonymized names by increasing latitude and longitude. During the past 100 years, 523 names have been used to record benthic foraminifera in the study area. Through synonymization, this number was reduced to 404, of which 138 occur at 6 or more of the 157 sample localities. Computer-generated maps were drawn for the 138 most commonly recorded species. Species were grouped by depth and geographic (latitudinal) distribution through visual examination of the maps. Eight species are coastal in their distribution, 63 occur mainly at depths of less than 200 m, 27 at depths greater than 200 m, and 40 are ubiquitous with depth. Many species appear to alter their depth distribution with latitude, but this may be due to a poor sampling framework. Latitudinally, the species are grouped into three categories. Forty-two species occur mainly to the north of 52°-55°N, 22 species occur mainly to the south of 52°-55°N, and 74 species are latitudinally ubiquitous within the area of study. This preliminary analysis indicates a possible faunal break in the region of Queen Charlotte Island. Description: Files listed include high and low resolution reproductions.

Although plate motion is generally considered as an explanation, this structurally complex region remains poorly defined. To interpret better the Neogene evolution, we prepared a detailed bathymetric chart and a map showing structural provinces and post-Miocene sediment patterns, which are constructed on the basis of seismic data (primarily a dense network of 30 KJ Sparker and 3.5 kHz profiles). The data suggest that the present-day configuration of the Tunisian and Sardinian margins results, in large part, from the contact of the southern part of the Corsican-Sardinian microplate with North Africa. Several dominant structural-stratigraphic trends are recognized in this study area: (1) NNW-SSE and NW-SE trends in the northwestern part of the study area are most likely related to the formation of the Algero-Balearic Basin since the late Oligocene. (2) Pronounced NNE-SSE trending structural axes (largely normal faults) are related to the near-parallel (N-S) tilted fault blocks in the Tyrrhenian Sea east of Sardinia. One of these tectonic structures on the margin east of Sardinia may possibly extend southward (190° - 200°) onto, and across, the Tunisian margin. The largest, most obvious physiographic features south of Sardinia, including seamounts, ridges, and canyons, are associated with these trends. These features, for the most part of middle to upper Miocene age, are believed closely related to the opening and subsidence of the Tyrrhenian Sea. (3) Morphological, structural, and stratigraphic-sedimentary trends, particularly off Tunisia, suggest Pliocene-Quaternary compression (E-W trending tectonics and depositional axes), resulting from the northward movement of Africa. (4) Important NW-SE structural-depositional trends (many extensional, some strike-slip) of Miocene to Quaternary age dominate the Strait of Sicily area east of Tunisia and south of Sicily. These may be related to displacement along the Calabrian-Sicilian Arc and to a collisional regime between the arc, the Corsican-Sardinian block, and African margin. We believe that the present configuration of the two margins resulted from plate contact and welding during several major Miocene events and also from subsidence, first, of the Algero-Balearic Basin and, then, of the Tyrrhenian Sea. In theory, the Tunisian margin and adjacent land have been subjected to compression as a result of seafloor spreading and collision. The physiographic trends and subsurface structural-stratigraphic configuration we map, however, reveal a predominance of Neogene to Recent structures, primarily of extensional origin.

Abstract: A computer file of all published (presence or absence) distributional data on the living and dead recent benthic foraminifera in the Gulf of Mexico was constructed from 77 papers published since 1918. Manipulation of this file produced 5 catalogs and 296 maps. Catalog 1 lists alphabetically species names with publication and locality information as recorded in the literature (i.e., unsynonymized). Catalog 2 lists synonymized species names (in the same numerical line order as Catalog 1) with publication and locality information. Catalogs 3 and 4 list alphabetically all unsynonymized and synonymized species names, respectively. Catalog 5 lists synonymized names by increasing latitude and longitude. During the past 60 years, 1219 names have been used to record benthic foraminifera in the Gulf of Mexico. Through synonymization, these were reduced to 848 species, of which 295 occur at 16 or more of the 426 sample localities. Computer-generated maps were drawn for these 295 most commonly recorded species. Species were grouped by depth and geographic distribution through visual examination of the maps. Twenty overlapping categories describe the depth distribution of the commonly recorded species. The depth distribution of 15 species varies considerably around the Gulf. Geographically the 295 most commonly recorded species may be grouped into 11 categories. Forty-eight percent of the species are ubiquitous around the Gulf. Circum-Gulf of Mexico provincial boundaries cannot be recognized but preliminary analysis distinguishes concentric benthic foraminiferal provinces whose margins can be related to particular depths and physiographic regions.

Abstract: Records of the benthic marine algae of the Island of Taiwan and neighboring islands have been organized in a floristic listing. All publications with citations of benthic marine green algae (Chlorophyta), brown algae (Phaeophyta), and red algae (Rhodophyta) in Taiwan are systematically arranged under the currently accepted nomenclature for each species. The annotated list includes names of almost 600 taxa, of which 476 are recognized today. In comparing the three major groups, the red algae predominate with 55% of the reported species, the green algae comprise 24%, and the browns 21%. Laurencia brongniartii J. Agardh is herein reported for Taiwan for the first time. The history of modern marine phycology in the Taiwan region is reviewed. Three periods of phycological research are recognized: the western (1866-1905); Japanese (1895-1945); and Chinese (1950-present). Western phycologists have apparently overlooked the large body of Japanese studies, which included references and records of Taiwan algae. By bringing together in one place all previous records of the Taiwanese marine flora, it is our expectation that this work will serve as a basis for further phycological investigations in the western Pacific region.

Abstract: This document is designed to serve as the catalog for a complete set of lithologic logs of 87 sediment borings drilled in the northern Nile delta of Egypt in the course of the Nile Delta Project, from 1985 to 1994. The project, part of the Mediterranean Basin (MEDIBA) Program, was initiated to interpret the recent geological evolution of this depocenter, from the time of its formation about 8000 years ago to the present. The data set includes the major petrologic attributes of these borings, which range in length from ~20 to 60 m. The results of textural and sand-sized compositional analyses of 2500 core samples are provided, as well as the ages of 358 radiocarbon-dated samples to as old as ~35,000 years before present. These data constitute the foundation of the Nile Delta Project's investigation. A review of the methods employed in the field and laboratory and an inventory of published articles and theses completed through 1994 as part of this multidisciplinary and multinational effort also are presented. This database facilitates the distinction between anthropogenic and natural factors that determine the evolution of the delta. It is intended to provide a comprehensive record of subsurface deposits in the northern delta, accumulating in late Pleistocene to Holocene time, to be used by those agencies and specialists responsible for monitoring the rapidly changing Nile delta depocenter.

Craig; Staples, Stephanie A.; Adey, Walter H. Abstract: A detailed geomorphic study was conducted along the glaciated shoreline of Gouldsboro Bay, Maine. The purpose of this study was to classify and map the geomorphic features as a preliminary step in the investigation of the late Quaternary evolution of the area. The distribution of geomorphic features was determined by the interpretation of vertical and oblique aerial photographs and ground-truth maps. For easier descrimination, the dominant coastal geomorphic features are separated into high- and low-intertidal regions. The high-intertidal features are defined by a distinct combination of sediment/bedrock type, geometry, and size. The major feature in this intertidal region are pocket beach, linear fringing beach, marsh, and exposed bedrock. The low-intertidal features are distinguished by differences in sediment type and grain size. Mud flat, mud/rock flat, sand/rock flat, rock ledge, and mussel bar are the significant features in this intertidal region. The geomorphology of Gouldsboro Bay is a function of three components. First, the Paleozoic bedrock lithology and structure, modified by late Cenozoic dissection and erosion, is the major component determining the regional coastal geomorphology. Second, the distribution pattern of late Wisconsin glacial moraines controls the dispersion of sediment, which strongly influences the local shoreline geomorphology. Third, the physical factors of wave exposure and winter ice effects are important processes that modify shoreline geomorphology. In turn, the degree of influence by these two physical factors is a function of shoreline orientation and fetch. Based on the interaction of these three components, Gouldsboro Bay can be broken into three distinct geomorphic zones: an exposed, seaward zone, a semi-exposed, central zone, and a protected, landward zone. This geomorphic classification appears suitable for the remainder of coastal Maine, and may have a wide application in areas such as the interpretation of stratigraphic sequences and the distribution of biological communities.
