Title: Eocene gastropods of Western Kamchatka- implications for high-latitude North Pacific biostratigraphy and biogeography.
Creator: Oleinik, Anton E.
Abstract/Description: Fossiliferous rocks of the Snatolskaya and Kovachinskaya formations comprise a Middle and Late Eocene shallow-marine record of the central part of western Kamchatka. Gastropod assemblages of these formations contain taxa that are conspecific with those in Paleogene strata of western North America and Japan, as well as a large percentage of endemic species. Analysis of the latitudinal ranges and worldwide occurrences of gastropod genera from these formations show the presence of three...
Show moreFossiliferous rocks of the Snatolskaya and Kovachinskaya formations comprise a Middle and Late Eocene shallow-marine record of the central part of western Kamchatka. Gastropod assemblages of these formations contain taxa that are conspecific with those in Paleogene strata of western North America and Japan, as well as a large percentage of endemic species. Analysis of the latitudinal ranges and worldwide occurrences of gastropod genera from these formations show the presence of three biogeographic components: cosmopolitan, North Pacific, and endemic. No Tethyan, or circumtropical genera are present in these Kamchatkan Middle and Late Eocene gastropod faunas. Changes in the geographic distribution of North Pacific gastropod assemblages through the Middle and Late Eocene indicate that only eastern Pacific Tethyan taxa were subjected to latitudinal range reduction. The distribution of cosmopolitan and North Pacific elements did not significantly change from the Middle to Late Eocene, which suggests a relatively stable environment and climate stability during that time. High-latitude Eocene gastropod assemblages from Western Kamchatka demonstrate a high level of endemism at the species level and a low-level of endemism on the genus level. This pattern is thought to be a result of the unrestricted migration of cosmopolitan taxa northward along the shallow-marine margin of the Pacific rim.

Title: The Genus Fulgoraria (Gastropoda: Volutidae) of the northeastern Kamchatka Peninsula and Sakhalin Island, with notes on the paleoecology and distribution of the subfamily Fulgorariinae in the Oligocene of the northern Pacific.
Creator: Oleinik, Anton E.
Abstract/Description: A review of the Oligocene biogeography of northern fulgorariines along the northern Pacific margin, including the western coast of North America, indicates that this subfamily had a much broader distribution during late Paleogene time than today. These data point to more favorable climatic conditions (including lower water temperatures) for dispersal of fulgorariine volutes during the Oligocene.

Establishing a sand spectral library is the first step in this process. Hyperspectal analysis allows for rapid, nondestructive data acquisition. This process uses an ASD spectrometer in a laboratory setting with an artificial light source to collect the spectra. Sand collected worldwide was also analyzed for grain size and composition.

Show moreQuantitative assessment of substrate classification for sand properties is needed for land management and conservation. Establishing a sand spectral library is the first step in this process. Hyperspectal analysis allows for rapid, nondestructive data acquisition. This process uses an ASD spectrometer in a laboratory setting with an artificial light source to collect the spectra. Sand collected worldwide was also analyzed for grain size and composition. Development of spectral libraries of sand is an essential factor to facilitate analytical techniques to monitor coastal problems including erosion and beach nourishment. This in turn can affect various flora and fauna which requires specific substrate to grow, nest, or live. Preliminary results show that each sand sample has a unique signature that can be identified using hyperspectral data.

The bathymetry and benthic environments of the study locality on the north-western margin of the Great Bahama Bank are discussed. A zoogeographic analysis indicates that the gastropod fauna in the vicinity of Victory Cay, Bimini Chain, Bahamas has a strong tropical affinity with a moderate influence from the temperate waters to the north.

Mollusks were collected from the Nuwok Member type section on the Arctic coast of Alaska. A systematic analysis was conducted to determine the position of Late Oligocene Arctic mollusks within a context of marine Cenozoic evolution and diversification. Oxygen stable isotope ratios of five fossil genera were used to calculate paleotemperatures and analyze growth histories. Taxa were selected to check for compatibility of results between fossil genera from the same environment. Oxygen stable isotope ratios of four recent high-latitude genera were analyzed for comparative purposes. Isotopically derived paleotemperatures represent the first documented quantitative temperatures for the Late Oligocene Arctic Ocean. Isotopic and systematic results give great insight into the extent and degree of Arctic cooling by the Late Oligocene and the origin of modem Arctic mollusks.

Comparison between isotopic signatures in recent and fossil congeneric species allowed substantial insight into growth rates. Recent specimens were collected from the Gulf of Aniva, Gulf of California, Bahamas, Florida Keys, and Gulf of Mexico. Fossil specimens were collected from the Middle Miocene of Kamchatka and the Pleistocene of Florida. Oxygen isotope ratios were also used to infer ambient seawater temperatures during the deposition of each shell. The calculated temperatures offer significant insight into the Pleistocene southern Florida embayment and Middle Miocene climatic optimum in the North Pacific.

The continuous section ofthe Tugidak Formation crops out in the sea cliffs along the northern and southwestern parts of the island and is the most complete section in the Trinity Islands. The exposed section of the Tugidak Formation is composed of 1395 m of glacial marine diamictite containing abundant molluscan fossils. Seismic profiles and well data indicate a regionally extensive deposition of the Tugidak Formation across the Kodiak Shelf. Paleomagnetic sampling and diatom analysis in this work has further refined the age of the Tugidak Formation as early-middle Pleistocene. By attempting a reconstruction of the tectonic evolution and through faunal identification, inferences are made about the paleobiogeography, paleoclimate and timing of sedimentary depositional cycles, around Tugidak Island.

A collection of recent A. borealis specimens from Camden Bay, northern Alaska (641 specimens) with outline intact were used for analyses. Bivariate analysis of height vs. length and morphometric analysis of shell outline determined variants within a population of A. borealis, and then compared to Pliocene A. borealis and Oligocene A. martini. The computer program SHAPE uses elliptic Fourier coefficients of shell outline to evaluate and visualize shape variations. The multivariate outline analysis indicates that A. borealis intraspecies variation is based upon a common shape that grades into other shapes, rather than grade between two or more end-forms.

Show moreBenthic foraminifera are exceptional organisms with distinctive features that allow for interpretation of both past and present environmental conditions. Some benthic foraminifera are widely distributed while some are restricted to specific environments due to their way of life. Foraminiferal assemblages south of Biscayne Bay and north of Cape Canaveral have previously been investigated; however, a gap exists in data covering a transitional zone along the Florida coast between the tropical waters of the western Atlantic and the cooler coastal waters along the North American coast. The purpose of this study was to collect baseline data on the benthic foraminifera of the small marine environment off of Pompano Beach that falls within this zone. This environment has a very particular relict reef system that includes a near-shore ridge complex, the unique foraminiferal assemblage of which has not been documented. Thirteen rubble samples were collected from this near shore ridge complex between October 2013 and April 2015 from depths of 2.5m – 9m. Abundances and diversity indices were calculated, and multivariate analysis and SHEBI analysis carried out to summarize baseline data for the area. Substrate types and seasonal collections were compared with foraminiferal abundances to determine if benthic foraminifera diversity varied between the four substrate types found on the near-shore ridge and between wet and dry seasons in Florida. Results revealed a variation in abundances for both substrates and seasons with the dominant genera being Quinqueloculina, Laevipeneroplis, and Archaias. Multivariate analysis displayed dissimilarities between substrates colonized by corals and those that were uncolonized. Comparison of studies from surrounding areas revealed fewer, however similar, species and different dominant genera. Overall, this area has proven to be a different environment compared to surrounding coastal areas and merits further investigation.

Stratigraphy is divided into four sequences. The organic rich shales are characterized as potential source rocks and the carbonates and marine to non marine sandstones are interpreted to be the reservoir rocks. Structural interpretation has revealed the presence of five structures capable of trapping hydrocarbons. These structures were identified as the Barrow arch, Camden anticline, Dinkum graben, shale diapirs and normal faults. The combination of these structures and stratigraphy offer petroleum exploration companies a promising target for large accumulations of hydrocarbons.

Off the coast of Pompano Beach, Florida, a Holocene storm deposit contains large accumulations of subfossil Acropora palmata fragments with these same encrusting organisms attached to their surfaces. The objective of this research was to create an inventory of encrusters found within the storm deposit and document their successional outgrowth to determine the post-depositional history of sampled coral fragments. Foraminifera and coralline algae were the most common species found, and various sequences of successional outgrowth were observed that indicated fragments were either deposited gradually, immediately buried, or reworked after initial burial. This information is vital for understanding modern biodiversity on the Pompano coast, and the development of nearshore benthic marine ecosystems during the mid-late Holocene.

Between 2021 and 2022, sediment samples were also collected from each of the bottom types to study mollusk diversity patterns. This combination of survey methods resulted in the identification of 325 species of hard-shelled mollusks, representing 103 families and 4 classes. To test for differences in community structure between bottom types, relative abundance data from the sediment samples was used for multivariate analyses including NMDS ordination, ANOSIM, and hierarchical cluster analysis. Results indicated statistically significant differences in mollusk species composition between NRC bottom types.

Sand, though an important unconsolidated material with great abundance on the Earth’s surface, is largely overlooked in spectroscopic studies. Over 100 sand samples were analyzed through traditional microscopic methods and compared to spectral reflectance collected via an ASD Spectroradiometer. Multiple methods were chosen to compare spectroscopic data to sand composition and grain size: 1) existing spectral indices, 2) continuum removal, 3) derivative analysis, and 4) correlation analysis. Particular focus was given to carbonate content. Results from derivative and correlation analysis showed strong correlations in the 2180-2240 nm and 2300-2360 nm windows to carbonate content. Proposed here is the Normalized Difference Carbonate Sand Index (NDCSI), which showed Pearson correlations of r=-0.78 for light-colored samples and r=-0.77 for all samples used. This index is viable for use with carbonate-rich sands.
