Succession Of Microbial Populations And Nitrogen-Fixation Associated With The Biodegradation Of Sediment-Oil-Agglomerates Buried In A Florida Sandy Beach, Boryoung Shin, Ioana Bociu, Max Kolton, Markus Huettel, Joel E Kostka
C-IMAGE Publications
The Deepwater Horizon (DWH) oil spill contaminated coastlines from Louisiana to Florida, burying oil up to 70 cm depth in sandy beaches, posing a potential threat to environmental and human health. The dry and nutrient-poor beach sand presents a taxing environment for microbial growth, raising the question how the biodegradation of the buried oil would proceed. Here we report the results of an in-situ experiment that (i) characterized the dominant microbial communities contained in sediment oil agglomerates (SOAs) of DWH oil buried in a North Florida sandy beach, (ii) elucidated the long-term succession of the microbial populations that developed in …

A Combined-Method Approach To Trace Submarine Groundwater Discharge From A Coastal Karst Aquifer In Ireland, Philip Schuler, L. Stoeckl, P. A. Schnegg
KIP Articles
Knowledge about the hydraulic connections between submarine groundwater discharge (SGD) and its terrestrial coastal catchment is relevant with regard to the management of marine and coastal waters in karst areas. This study applies different methods and monitoring approaches to trace SGD between the Burren Limestone Plateau and Galway Bay in western Ireland, via an excavated sinkhole shaft and deep conduit. Areas of potential SGD were first delineated based on sea surface temperature anomalies using Landsat satellite images. Two fluorescent dyes and solid wood chips were then used as tracers. Solid wood chips were tested as potential means to circumvent the …

Prior to the Deepwater Horizon oil spill, we lacked a comprehensive baseline of oil contamination in the Gulf of Mexico's sediments, water column, and biota. Gaps in prespill knowledge limit our ability to determine the aftereffects of the Deepwater Horizon blowout or prepare to mitigate similar impacts during future oil spill disasters. We examined spatiotemporal differences in exposure to and metabolism of polycyclic aromatic hydrocarbons (PAHs) in 2 hake species (Urophycis spp.) to establish a current baseline for these ecologically important, abundant, and at-risk demersal fishes. Gulf hake (Urophycis cirrata) and southern hake (Urophycis floridana) were collected throughout the Gulf …

Physicochemical And Colligative Investigation Of Α (Shrimp Shell)-And Β (Squid Pen)-Chitosan Membranes: Concentration-Gradient-Driven Water Flux And Ion Transport For Salinity Gradient Power Andseparation Process Operations, Clifford R. Merz
Marine Science Faculty Publications
Chitin, and its derivative chitosan, is a naturally occurring biopolymer and an abundant polysaccharide containing acetylated units of N-acetyl-d-glucosamine. Chitosan membranes produced from shrimp shell (α) and squid pen (β) biowaste were prepared by solvent-casting, after which water flux and ionic transport diffusion experiments were conducted using a side-by-side concentration test cell under differing salinity concentration gradients. Physicochemical and experimental investigations were conducted, which confirmed that β-chitin possesses differing and enhanced performance characteristics than α-chitin with respect to diffusive water flux and ionic transport capabilities. In addition, novel colligative investigations through osmotic equilibrium were conducted to determine electrochemical characteristics …

Licensee MDPI, Basel, Switzerland. The preventive effect of high-dose (9%) regular-fish oil (FO) against bone loss during aging has been demonstrated, but the effects of a low-dose (1%–4%) of a highly purified concentrated FO (CFO) has not been elucidated. The aim of this study was to determine the dose-dependent effect of a CFO against bone loss in C57BL/6 female mice during aging. Twelve-month old mice were fed with 1% and 4% CFO and 4% safflower oil (SFO) diets, including a group with a 4% regular-FO diet and a group with a lab chow diet for 12 months. Bone mineral density …

Improving The Integration Of Restoration And Conservation In Marine And Coastal Ecosystems: Lessons From The Deepwater Horizon Disaster, Richard L. Wallace, Gilbert Gilbert, John E. Reynolds Iii
Improving The Integration Of Restoration And Conservation In Marine And Coastal Ecosystems: Lessons From The Deepwater Horizon Disaster, Richard L. Wallace, Gilbert Gilbert, John E. Reynolds Iii
C-IMAGE Publications
In the wake of the Deepwater Horizon disaster, much has been learned about the biological, ecological, physical, and chemical conditions of the Gulf of Mexico. In parallel, the research community has also gained insight about the social and organizational structures and processes necessary for oil spill response and subsequent marine and coastal restoration. However, even with these lessons from both the Deepwater Horizon and previous spills, including 1989’s Exxon Valdez and the Ixtoc 1 in 1979, our understanding of how to avoid future crises has not advanced at the same pace as offshore oil and gas development. We argue that …

School of Geosciences Faculty and Staff Publications
Measuring seafloor motion in shallow coastal water is challenging due to strong and highly variable oceanographic effects. Such measurements are potentially useful for monitoring near‐shore coastal subsidence, subsidence due to petroleum withdrawal, strain accumulation/release processes in subduction zones and submerged volcanoes, and certain freshwater applications, such as volcano deformation in caldera‐hosted lakes. We have developed a seafloor geodesy system for this environment based on an anchored spar buoy topped by high‐precision GPS. Orientation of the buoy is measured using a digital compass that provides heading, pitch, and roll information. The combined orientation and GPS tracking data are used to recover …

Submesoscale And Mesoscale Eddies In The Florida Straits: Observations From Satellite Ocean Color Measurements, Yingjun Zhang, Chuanmin Hu, Yonggang Liu, Robert H. Weisberg, Vassiliki H. Kourafalou
Marine Science Faculty Publications
Despite their well-recognized importance in driving ocean physics and biology, submesoscale (diameter < Rossby radius of deformation) eddies have been extremely difficult to observe due to technical difficulties from both field and remote platforms. Here using novel satellite ocean color data products and modified algorithms, we address this challenge for the Florida Straits (22–28°N, 78–85°W). Between 2002 and 2018, while mesoscale eddies (radius >15 km) show strong seasonality with occurrence frequency decreasing from Lower Keys to Upper Keys, submesoscale eddies show little or no seasonality with high occurrence frequency restricted to 30–200-m isobaths. The number of mesoscale eddies decreases exponentially in size, but submesoscale eddies show a normal distribution in size. These findings are significant in filling our knowledge gap in submesoscale eddies in this physically and ecologically important region as it encompasses world-renowned coral reefs, seagrasses, and fisheries.

Faunal assemblages at hydrothermal vents associated with island-arc volcanism are less well known than those at vents on mid-ocean ridges and back-arc spreading centres. This study characterizes chemosynthetic biotopes at active hydrothermal vents discovered at the Kemp Caldera in the South Sandwich Arc. The caldera hosts sulfur and anhydrite vent chimneys in 1375–1487 m depth, which emit sulfide-rich fluids with temperatures up to 212°C, and the microbial community of water samples in the buoyant plume rising from the vents was dominated by sulfur-oxidizing Gammaproteobacteria. A total of 12 macro- and megafaunal taxa depending on hydrothermal activity were collected in these …

A Relictual Troglomorphic Harvestman Discovered In A Volcanic Cave Of Western Argentina: Otilioleptes Marcelae, New Genus, New Species, And Otilioleptidae, New Family (Arachnida, Opiliones, Gonyleptoidea), Luis E. Acosta
KIP Articles
The troglomorphic harvestman Otilioleptes marcelae gen. nov., sp. nov. from the basaltic cave Doña Otilia, Payunia region, Mendoza Province, Argentina, is described. Its systematic affinities were studied through cladistic and Bayesian analyses that included representatives of Gonyleptoidea; it was determined to represent a new monotypic family, Otilioleptidae fam. nov., occupying a basal position within the clade Laminata. This species shows accentuated troglomorphic traits, typical for troglobitic harvestmen: elongated appendages, depigmentation, reduction of eyes and fading of scutal sulci. Additionally, it almost lacks sexual dimorphism, the distal portion of coxa IV is not completely fused to the stigmatic segment, and penis …

Microliths In The South Asian Rainforest ~45-4 Ka: New Insights From Fa-Hien Lena Cave, Sri Lanka, Oshan Wedage, Andrea Picin, James Blinkhorn
KIP Articles
Microliths–small, retouched, often-backed stone tools–are often interpreted to be the product of composite tools, including projectile weapons, and efficient hunting strategies by modern humans. In Europe and Africa these lithic toolkits are linked to hunting of medium- and large-sized game found in grassland or woodland settings, or as adaptations to risky environments during periods of climatic change. Here, we report on a recently excavated lithic assemblage from the Late Pleistocene cave site of Fa-Hien Lena in the tropical evergreen rainforest of Sri Lanka. Our analyses demonstrate that Fa-Hien Lena represents the earliest microlith assemblage in South Asia (c. 48,000–45,000 cal. …
