Analysis Of The Magnetic Signature Of Surface Waves Measured In A Laboratory Experiment, John Kluge, Alex Soloviev, Cayla W. Dean, Geoffrey K. Morrison, Brian K. Haus
Analysis Of The Magnetic Signature Of Surface Waves Measured In A Laboratory Experiment, John Kluge, Alex Soloviev, Cayla W. Dean, Geoffrey K. Morrison, Brian K. Haus
Marine & Environmental Sciences Faculty Articles
A magnetic signature is created by secondary magnetic field fluctuations caused by the phenomenon of seawater moving in Earth’s magnetic field. A laboratory experiment was conducted at the SUrge STructure Atmosphere INteraction (SUSTAIN) facility to measure the magnetic signature of surface waves using a differential method: a pair of magnetometers, separated horizontally by one-half wavelength, were placed at several locations on the outer tank walls. This technique significantly reduced the extraneous magnetic distortions that were detected simultaneously by both sensors and additionally doubled the magnetic signal of surface waves. Accelerometer measurements and local gradients were used to identify magnetic noise …
Spatial And Temporal Patterns Of Fire On Saipan, Cnmi, Ilan E. Bubb, Zachary B. Williams
Spatial And Temporal Patterns Of Fire On Saipan, Cnmi, Ilan E. Bubb, Zachary B. Williams
Marine & Environmental Sciences Faculty Articles
Sediment core studies from Saipan suggest that fires did not play a prominent role in the disturbance regime of the Mariana Islands and have increased in frequency since human settlement around 4,000 years ago. On Saipan fires are understood to interrupt the pattern of succession leading to the degradation of native limestone forests, the proliferation of grasslands and the eventual creation of badlands. Little baseline data regarding the spatial and temporal patterns of fire on Saipan exist to create effective Fire Management Plans. This project uses Landsat 8 images from April 2013 to July 2020 and the Normalized Burn Ratio …

Drift macroalgae plays key roles in the ecology of many coastal systems, including the Indian River Lagoon. In the lagoon, changes in the biomass of drift macroalgae may have interacted with an unprecedented bloom of phytoplankton in 2011. Patterns in the biomass of drift macroalgae were identified using new and original analyses of data from several sampling programs collected between 1997 and 2019. All available data show a relatively low biomass of drift macroalgae in 2010–2012, and surveys of fixed transects and seining as part of a fisheries independent monitoring program also recorded low biomass in 2016. Low light availability …

The Biological Condition Gradient (BCG) is a conceptual model used to describe incremental changes in bio- logical condition along a gradient of increasing anthropogenic stress. As coral reefs collapse globally, scientists and managers are focused on how to sustain the crucial structure and functions, and the benefits that healthy coral reef ecosystems provide for many economies and societies. We developed a numeric (quantitative) BGC model for the coral reefs of Puerto Rico and the US Virgin Islands to transparently facilitate ecologically meaningful management decisions regarding these fragile resources. Here, reef conditions range from natural, undisturbed conditions to severely altered or …

Shore-based submersible operations, from 2006 to 2020, have allowed us to examine megabenthic assemblages along the island margin of Isla de Roatán from depths of about 150 to 750 m, including repeated observations of the same organisms. These dives were used to photo-document a diverse benthic assemblage and observe the health and condition of the sessile fauna in a well-explored but relatively undocumented area of the Mesoamerican Reef. Samples were collected by dip net, and some dives profiled the water column chemistry in the year 2011. The deep-sea coral assemblage observed off Roatan exhibits high abundance and diversity. The sessile …

Coral reef metabolism underpins ecosystem function and is defined by the processes of photosynthesis, respiration, calcification, and calcium carbonate dissolution. However, the relationships between these physiological processes at the organismal level and their interactions with light remain unclear. We examined metabolic rates across a range of photosynthesising calcifiers in the Caribbean: the scleractinian corals Acropora cervicornis, Orbicella faveolata, Porites astreoides, and Siderastrea siderea, and crustose coralline algae (CCA) under varying natural light conditions. Net photosynthesis and calcification showed a parabolic response to light across all species, with differences among massive corals, branching corals, and CCA that …

[Chapter Abstract] 230Coral reefs provide critical ecological and geomorphic (e.g. sediment production for reef-fronted shoreline maintenance) services, which interact in complex and dynamic ways. These services are under threat from climate change, requiring dynamic modelling approaches that predict how reef systems will respond to different future climate scenarios. Carbonate budgets, which estimate net reef calcium carbonate production, provide a comprehensive ‘snap-shot’ assessment of reef accretionary potential and reef stability. These budgets, however, were not intended to account for the full suite of processes that maintain coral reef services or to provide predictive capacity on longer timescales (decadal to centennial). To …

Ubiquitous Microplastics In The Upper Gastrointestinal Tracts Of Florida Coastal Seabirds, Jonathan J. Clark, Dorothy-Ellen A. Renegar, Dave Kerstetter
Ubiquitous Microplastics In The Upper Gastrointestinal Tracts Of Florida Coastal Seabirds, Jonathan J. Clark, Dorothy-Ellen A. Renegar, Dave Kerstetter
Marine & Environmental Sciences Faculty Articles
Plastic pollution is increasingly recognized as a global problem. In particular, plastic pieces <5 mm in size (‘microplastics’) are of interest due to their prevalence and association with harmful, persistent organic pollutants (POPs). Very little is known about the prevalence of microplastics in coastal birds. Yet, these water-associated birds are at a high risk of ingesting microplastics that accumulate near the water’s surface. This study describes the microplastics found in the proventriculus and ventriculus of four species of coastal birds regarding quantity, size, type (fiber or fragment), and color (light, mid, or dark). A total of 643 microplastic particles were identified, with 43 of the 44 study specimens containing microplastics (97.7% frequency). The ‘fiber’ type and the ‘mid’ color were the most common microplastics. There were no significant differences between species for particle sizes, but Brown Pelicans contained significantly more particles than the other three species. These results highlight the prevalence of plastic pollution in medium-sized seabirds, but more work is needed to determine microplastic patterns between taxa and foraging environments.

Implications Of Salinity Normalization Of Seawater Total Alkalinity In Coral Reef Metabolism Studies, Travis A. Courtney, Tyler Cyronak, Alyssa J. Griffin, Andreas J. Andersson
Marine & Environmental Sciences Faculty Articles
Salinity normalization of total alkalinity (TA) and dissolved inorganic carbon (DIC) data is commonly used to account for conservative mixing processes when inferring net metabolic modification of seawater by coral reefs. Salinity (S), TA, and DIC can be accurately and precisely measured, but salinity normalization of TA (nTA) and DIC (nDIC) can generate considerable and unrecognized uncertainties in coral reef metabolic rate estimates. While salinity normalization errors apply to nTA, nDIC, and other ions of interest in coral reefs, here, we focus on nTA due to its application as a proxy for net coral reef calcification and the importance for …
Optimizing The Time To Transfer Sexually Produced Corals Of Porites Astreoides, Agaricia Agaricites, And Montastraea Cavernosa To An Offshore Nursery, Rachel Ionata
All HCAS Student Capstones, Theses, and Dissertations
As reefs continue to decline globally and become unable to recover on their own, restoration becomes essential to abate reef degradation and boost reef recovery until the main sources of the degradation are addressed. Sexual propagation is an important restoration technique that still requires optimization. One of the major knowledge gaps is determining the optimal time to transfer newly-settled sexually-produced corals from an aquarium to an offshore nursery without compromising their survival and growth. This study transferred settlers from Porites astreoides, Agaricia agaricites, and Montastraea cavernosa to an offshore nursery at approximately one week, five weeks, and nine weeks post-settlement, …

Predation Efficiency Of Lionfish (Pterois Volitans And P. Miles) In Differing Levels Of Habitat Complexity, Abigail Ehlers Kimbrel
All HCAS Student Capstones, Theses, and Dissertations
The invasion of the Indo-Pacific lionfish (Pterois sp.) into the Atlantic and Caribbean has received attention around the globe. Venomous spines, over-sized fanlike pectoral fins, slow movement, and novel feeding strategies have allowed lionfish to become effective apex- predators. Recent research has determined that lionfish use inshore mangrove habitats as foraging grounds, which are also used as nursery habitats for juvenile fish, thus reducing recruitment of native fish populations. The purpose of this study was three-fold: (1) determine the predation efficiency of lionfish in differing mangrove habitat complexities, (2) examine the influence of temperature and behavior of prey commonly found …

Accurately predicting the effects of ocean and coastal acidification on marine ecosystems requires understanding how responses scale from laboratory experiments to the natural world. Using benthic calcifying macroalgae as a model system, we performed a semi-quantitative synthesis to compare directional responses between laboratory experiments and field studies. Variability in ecological, spatial, and temporal scales across studies, and the disparity in the number of responses documented in laboratory and field settings, make direct comparisons difficult. Despite these differences, some responses, including community-level measurements, were consistent across laboratory and field studies. However, there were also mismatches in the directionality of many responses …

Element Contamination In Port Everglades – Preparing For Ecological Impacts, Laura White
All HCAS Student Capstones, Theses, and Dissertations
Port dredging is of economic importance worldwide but its impacts to the marine environment through the remobilization of elemental contaminants are not well understood. A massive deepening and widening of Port Everglades, Florida, will begin in 2023. Contaminated sediment disturbed during the dredging process could be released and prove to be harmful to three coral reef tracks located beginning 1.5 miles away from the port. This study focused on identifying and quantifying 14 different trace elements: arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), mercury (Hg), lead (Pb), manganese (Mn), molybdenum (Mo), nickel (Ni), selenium (Se), tin (Sn), …

The Deepwater Horizon (DWH) oil spill occurred in a region of the Gulf of Mexico (GoM) supporting abundant, diverse and valuable communities of fishes and fishers. The economy of the northern GoM is inextricably tied to the natural resource bases of the region (tourism, fishing, oil and gas, etc.) and thus the coupling between the human and ecological systems is tight and subject both feed-back and, to some extent, feed-forward controls. Management actions taken during the 87-day DWH spill incident included the closure of over 280,000 km2 of productive fishing area (about 1/3 of USA federal waters in the …

Pelagic Habitat Use By Benthic Fishes – Juvenile Scorpaenoids Of The Oceanic Gulf Of Mexico, Drew W. Mertzlufft
All HCAS Student Capstones, Theses, and Dissertations
The suborder Scorpaenoidei is among the most speciose fish taxa of the World Ocean, including the Gulf of Mexico (GoM). Most adult scorpionfishes are benthic and have a pelagic juvenile phase. Although the species descriptions and distributions of adult scorpionfishes within the GoM are well documented, their juvenile forms are largely undescribed. Due to the poorly resolved taxonomic status of juvenile scorpionfishes, their assemblage dynamics have not been accurately assessed. Specimens were collected from the GoM during seven research cruises (2010-2011), as part of the NOAA-supported Offshore Nekton Sampling and Analysis Program (ONSAP), and during six research cruises (2015-2018), as …

Nearshore coastal waters are highly dynamic in both space and time. They can be difficult to sample using conventional methods due to their shallow depth, tidal variability, and the presence of breaking waves. High resolution satellite sensors can be used to provide synoptic views of Surface Temperature (ST), but the performance of such ST products in the nearshore zone is poorly understood. Close to the shoreline, the ST pixels can be influenced by mixed composition of water and land, as a result of the sensor’s spatial resolution. This can cause thermal adjacency effects due to the highly different diurnal temperature …

Sesoko Station, Okinawa, has been the site of many significant advances in coral reproductive research and it continues to be a preferred destination for both Japanese and international researchers. Consequently, there are decades of spawning observations, which we present and explore here with the aim of making it easier to predict when species spawn at Sesoko Station. The data include over 700 spawning observations from 87 species of reef-building hermatypic corals. Almost all spawning occurred between dusk and dawn, with most spawning activity concentrated in the 2 to 4 hours after sunset. Some phylogenetic patterns were evident: most Acropora species …

Peru’s coastal waters are characterized by significant environmental fluctuation due to periodic El Niño- La Niña- Southern Oscillation (ENSO) events. This variability results in ecosystem-wide food web changes which are reflected in the tissues of the Peruvian fur seal (Arctocephalus australis). Stable isotope ratios (δ13C and δ15N) in Peruvian fur seal vibrissae (whiskers) are used to infer temporal primary production and dietary variations in individuals. Sea surface temperature anomaly (SSTA) recordings from the Niño 1+2 Index region captured corresponding ENSO conditions. Fluctuations in δ15N values were correlated to SSTA records, indicating that …
