Sea-level rise will drive divergent sediment transport patterns on fore reefs and reef flats, potentially causing erosion on Atoll Islands

James Bramante, Andrew D. Ashton, Curt D. Storlazzi, Olivia M. Cheriton & Jeffrey P. Donnelly
Atoll reef islands primarily consist of unconsolidated sediment, and their ocean-facing shorelines are maintained by sediment produced and transported across their reefs. Changes in incident waves can alter cross-shore sediment exchange and thus affect the sediment budget and morphology of atoll reef islands. Here we investigate the influence of sea-level rise and projected wave climate change on wave characteristics and cross-shore sediment transport across an atoll reef at Kwajalein Island, Republic of the Marshall Islands....

Causes of oceanic crustal thickness oscillations along a 74-Myr Mid-Atlantic Ridge flow line

William Shinevar, Hannah Mark, Fiona Clerc, Emmanuel A. Codillo, Jianhua Gong, Jean-Arthur Olive, Stephanie Brown, Paris T. Smalls, Yang Liao, Véronique Le Roux & Mark Behn
Gravity, magnetic, and bathymetry data collected along a continuous 1400-km-long spreading-parallel flow line across the Mid-Atlantic Ridge indicate significant tectonic and magmatic fluctuations in the formation of oceanic crust over a range of timescales. The transect spans from 28 Ma on the African Plate to 74 Ma on the North American plate, crossing the Mid-Atlantic Ridge at 35.8 ºN. Gravity-derived crustal thicknesses vary from 3–9 km with a standard deviation of 1 km. Spectral analysis...

Data from: Developmental exposure to PCB153 (2,2’,4,4’,5,5’-hexachlorobiphenyl) alters circadian rhythms and the expression of clock and metabolic genes

Neel Aluru, Keegan Krick, Adriane McDonald & Sibel Karchner
Polychlorinated biphenyls (PCBs) are highly persistent and ubiquitously distributed environmental pollutants. Based on their chemical structure, PCBs are classified into non-ortho-substituted and ortho-substituted congeners. Ortho-substituted PCBs are structurally similar to dioxin and their toxic effects and mode of action are well established. In contrast, very little is known about the effects of non-ortho-substituted PCBs, particularly during early development. The objective of this study is to investigate the effects of exposure to an environmentally prominent ortho-substituted...

Pathways to the Denmark Strait Overflow: A Lagrangian Study in the Iceland Sea

Marieke Femke de Jong, Amy Bower, Henrik Søiland, Heather Furey & Andree L. Ramsey
The goal of this project was to directly measure the dense water pathways upstream of the Denmark Strait in the Iceland Sea and compare the results to existing ideas about the dynamics of the circulation by deploying 45 acoustically tracked RAFOS floats over a two year time period (24-Jul-2013 to 29-May-2015). The floats were ballasted to drift at a target depth of 500m, recording pressure, temperature, and Times Of Arrivals (TOAs) every six hours or...

Data from: Trophic plasticity in a common reef-building coral: Insights from δ13C analysis of essential amino acids

Michael Fox, Emma Elliott Smith, Jennifer Smith & Seth Newsome
1. Reef-building corals are mixotrophic organisms that can obtain nutrition from endosymbiotic microalgae (autotrophy) and particle capture (heterotrophy). Heterotrophic nutrition is highly beneficial to many corals, particularly in times of stress. Yet the extent to which different coral species rely on heterotrophic nutrition remains largely unknown because it is challenging to quantify. 2. We developed a quantitative approach to investigate coral nutrition using carbon isotope (δ13C) analysis of six essential amino acids (AAESS) in a...

Data and numerical methods for determining the dynamics and kinematics of Newark Bay, NJ

W. Bryce Corlett, W. Rockwell Geyer, Robert Chant, David Ralston & Christopher K. Sommerfield
These observational data and numerical methods were used to investigate the subtidal salt balance of Newark Bay, a sub-estuarine network connected to the Hudson River estuary through New York Harbor. The moored data were collected in 2008 by Chant and Sommerfield, and in 2016 by Corlett, Geyer, and Ralston. Corlett devised the included numerical methods. Shipboard measurements of the vertical salinity profile near each mooring were used to reconstruct the tidally-varying vertical salinity profile from...

Hunting Bubbles Falkor Cruise 2019

Anna P. M Michel, Scott D. Wankel, David P. Nicholson, Kristen Fauria & Victoria Lynn Preston
The Hunting Bubbles Cruise took place in August-September 2018 on the R/V Falkor (cruise ID 180824). Ship time was provided by the Schmidt Ocean Institute. This cruise investigated transport of methane from seeps located on the Cascadia Margin. Data archived at the WHOAS repository supplements additional data from this cruise available at the R2R rolling deck to repository and at MGDS: Marine Geoscience Data System.

Observations of turbulence and the geometry and circulation of windrows in a small bay in the St. Lawrence Estuary.

Seth Zippel, Ted Maksym, Malcolm E. Scully, Peter Sutherland & Dany Dumont
Measurements of ocean turbulence, waves, and the geometry and circulation of windrows were made over 5 days in early March in a small bay in the St. Lawrence Estuary. Measurements were made from a small zodiac and from a SWIFT drifter. Two acoustic doppler velocity profilers (ADCPs) were used from the zodiac to measure water velocity and turbulent kinetic energy (TKE) dissipation rates near the surface. The acoustic backscatter from the ADCPs was used in...

Reducing effort in the U.S. American lobster (Homarus americanus) fishery to prevent North Atlantic right whale (Eubalaena glacialis) entanglements may support higher profits and long-term sustainability

Hannah Myers & Michael J. Moore
Supplemental data for Reducing effort in the U.S. American lobster (Homarus americanus) fishery to prevent North Atlantic right whale (Eubalaena glacialis) entanglements may support higher profits and long-term sustainability. Figure 5: Estimated North Atlantic right whale population, number of calves, observed mortalities and serious injuries, and diagnosed cause of death or serious injury. Diagnosed entanglements have increased significantly since the population has been in decline. Data from Waring et al. 1997, Kraus et al. 2001,...

Data from: Upwelling as the major source of nitrogen for shallow and deep reef-building corals across an oceanic atoll system

Veronica Z. Radice, Ove Hoegh-Guldberg, Brian Fry, Michael D. Fox & Sophie G. Dove
Oceanographic processes shape coral reefs worldwide by redistributing inorganic nutrients and particulate resources over depth. Deep‐water upwelling occurs frequently in coral reef ecosystems, but its impact on coral nutrition remains unclear. This study investigated the influence of upwelling on the trophic ecology of three common reef‐building corals (Galaxea fascicularis, Pachyseris speciosa and Pocillopora verrucosa) from different reef depths (shallow reef, 10 m, vs. deep reef, 30 m) and reef exposures (oceanic rim vs. Inner Sea)...

Data from: Estimating body mass of free-living whales using aerial photogrammetry and 3D volumetrics

Fredrik Christiansen, Mariano Sironi, Michael J. Moore, Matías Di Martino, Marcos Ricciardi, Hunter A. Warick, Duncan J. Irschick, Robert Gutierrez & Marcela M. Uhart
1. Body mass is a key life history trait in animals. Despite being the largest animals on the planet, no method currently exists to estimate body mass of free-living whales. 2. We combined aerial photographs and historical catch records to estimate the body mass of free-living right whales (Eubalaena sp.). First, aerial photogrammetry from unmanned aerial vehicles was used to measure the body length, width (lateral distance) and height (dorso-ventral distance) of free-living southern right...

Data from: A phylogenomic approach to clarifying the relationship of Mesodinium within the Ciliophora: a case study in the complexity of mixed-species transcriptome analyses

Erica Lasek-Nesselquist & Matthew D. Johnson
Recent high-throughput sequencing endeavors have yielded multi-gene/protein phylogenies that confidently resolve several inter- and intra-class relationships within the phylum Ciliophora. We leverage the massive sequencing efforts from the Marine Microbial Eukaryote Transcriptome Sequencing Project, other SRA submissions, and available genome data with our own sequencing efforts to determine the phylogenetic position of Mesodinium and to generate the most taxonomically-rich phylogenomic ciliate tree to date. Regardless of the data mining strategy, the multi-protein dataset, or the...
