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....

Quantifying pelagic primary production and respiration via automated in-situ incubation system

Solomon Chen & Matthew Long
We developed and validated a novel automated water incubator that measures in-situ rates of photosynthesis and respiration. This dataset includes raw data, Monte-Carlo simulation method, and processed results from field deployments in Summer, 2021. Deployment of the incubator was conducted near Ucantena Island, Massachusetts, USA. The dataset includes timeseries of automated incubation experiments, reporting dissolved oxygen concentration (DO), temperature, and photosynthetically active radiation (PAR). There are four deployments spanning from late august to early October,...

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 the 2018 dye release cruise south of Martha’s Vineyard, MA

Irina Rypina, Anthony Kirincich & Thomas Peacock
On Aug 16-17, 2018 a rhodamine dye experiment was conducted in the coastal ocean south of Martha’s Vineyard, MA. One of the experiment’s aims was to investigate the exchanges, or the absence of such, between the mixed layer and the ocean underneath over a time scale of about a day.

Discovering hydrothermalism from afar: in situ methane instrumentation and change-point detection for decision-making

Anna Michel, Scott Wankel, Victoria Preston, Genevieve E. Flaspohler, Jason Kapit, William A. Pardis, Sarah Youngs, Donald E. Martocello, Peter Girguis & Roy, Nicholas Roy, Nicholas
Seafloor hydrothermalism plays a critical role in fundamental interactions between geochemical and biological processes in the deep ocean. A significant number of hydrothermal vents are hypothesized to exist, but many of these remain undiscovered due in part to the difficulty of detecting hydrothermalism using standard sensors on rosettes towed in the water column or robotic platforms performing surveys. Here, we use in situ methane sensors to complement standard sensing technology for hydrothermalism discovery and compare...
