[Particulate bulk and amino acid d15N - EXPORTS May 2021] - Particulate bulk and amino acid d15N values from EXPORTS cruises on RRS Discovery (DY131) and RRS James Cook (JC214) in May 2021 (Collaborative Research: Isotopic Indicators for Mechanisms of Organic Matter Degradation under High Productivity and High Carbon Flux Conditions (EXPORTS))

This dataset presents bulk and compound-specific nitrogen stable isotope ratios of amino acids in size-fractionated and sinking particles from the Northeast Atlantic during the spring bloom decline as part of the second EXPORTS campaign. Size-fractionated particles were collected via in situ filtration and sinking particles were collected via sediment traps in May 2021. Size-fractionated particles were collected from 20 meters (m) to 500 m at various depths, depending on particle type. At 30 and 340 m, five size fractions were collected for both bulk and amino acids isotopic analysis: 0.3-1 micrometers (μm), 1-6 μm, 6-51 μm, 51-335 μm, and >335 μm. At 20, 50, 75 or 95, 125 or 145, 175 or 195, 330, and 500 m, two size fractions were collected for amino acid isotopic analysis: 0.8-51 μm particles and >51 μm particles. Particle data were used to determine major processes altering particulate organic matter. The collection of these data was supported by NSF.

[Particulate Carbon Concentrations and Stable Carbon Isotopes] - Particulate Carbon Concentrations and Stable Carbon Isotopes in Marine Particles Captured by In Situ Mclane Pumps at Cocos Ridge Coco Ridge (Eastern Equatorial Pacific) during cruise SR2113 between November - December 2021 (Collaborative Research: New approaches to study calcium carbonate dissolution on the sea floor and its impact on paleo-proxy interpretations)

This dataset includes particulate carbon concentrations and isotopes collected in December, 2021. Suspended particles are collected at 4 different stations near Cocos Ridge, at two different size fractions using Mclane pumps.  The two size fractions are large size fraction (LSF) that is >51 um, and small size fraction (SSF) that is 0.5 -- 51 um. Concentrations and stable carbon isotopes of particulate inorganic carbon (PIC) and total carbon (TC) are measured and reported. PIC content are measured by acidifying a subsample of the Glass Fiber Filter (GFF) and measuring total CO2 released using a Picarro Cavity Ring-down Spectroscopy. TC content are analyzed by burning a subsample of the GFF on Elemental Analyzer (EA). Samples were collected during SR2113 onboard Sally Ride, under the project "new approaches to study calcium carbonate dissolution on the sea floor and its impact on paleo-proxy interpretations", as a water-column side determination of particle compositions and carbonate dissolution. This data reveals changes in concentrations and stable carbon isotopes with water depth, and has implications for multiple biogeochemical processes associated with both the inorganic and the organic carbon within marine particles in the water column.

[Particulate metals from the scandium incubation experiment on PUPCYCLE I in the California Current System in 2019] - Particulate metals from a scandium incubation experiment during the PUPCYCLE I R/V Oceanus cruise 1905B in the California Current System in 2019 (CAREER: An integrated molecular and physiological approach to examining the dynamics of upwelled phytoplankton in current and changing oceans)

We performed an incubation experiment with added dissolved scandium and/or iron in waters sampled in the California Current System during the PUPCYCLE I cruise in 2019 with Chief Scientist Adrian Marchetti. PUPCYCLE I (Phytoplankton response to the UPwelling CYCLE) took place in summer 2019 onboard the R/V Oceanus (OC 1905b). Water for the incubation was collected from 15 m just off the Big Sur coast 2 June 2019. This was in a region with an extremely narrow shelf. There were five total treatments run in triplicate: control (no addition), +5 nmol/kg dissolved Fe, +5 nmol/kg dissolved Sc, +5 nmol/kg dissolved Fe and +5 nmol/kg dissolved Sc, and filtered seawater with +5 nmol/kg dissolved Fe and +5 nmol/kg dissolved Sc. After 24 hours incubating, the incubation was harvested and analyzed for chlorophyll, nutrients, and dissolved and particulate Fe and Sc concentrations. The effort was to investigate similarities and differences in the oceanic chemical cycling of Fe and Sc.

[Particulate Organic Matter from BVal58 Cruise] - Concentrations of particulate organic matter (POC, PON, POP, PCOD), total oxygen demand, POM ratios, and respiration ratios from samples collected on R/V Atlantic Explorer BATS validation study #58 in the Sargasso Sea in October 2021 (Quantifying ocean oxygen-to-carbon demand by chemical analyses and inverse models)

This dataset includes suspended concentrations of particulate organic carbon (POC), particulate organic nitrogen (PON), particulate organic phosphorus (POP), particulate chemical oxygen demand (PCOD), and total oxygen demand (Sigma_-O2 = PCOD + 2PON) down to a depth of 1000 meters (m) in the Sargasso Sea. This dataset also includes POM ratios (C/N, C/P, & N/P) and respiration ratios (PCOD/POC, Sigma_-O2/C, Sigma_-O2/N, & Sigma_-O2/P) with depth. These measurements were quantified from seawater samples collected aboard the R/V Atlantic Explorer as part of the Bermuda Atlantic Time-series Study Validation cruise #58 (BVal58). BVal58 started at St. George's, Bermuda on 11 October 2021 and the research group disembarked in San Juan, Puerto Rico on 21 October 2021. Euphotic zone samples (5 - 120 m) were collected using a CTD bottle rosette and disphotic zone samples (150 - 1000 m) were collected using large volume pumps.

Climate-induced ocean deoxygenation is increasing, but biological components of oxygen loss remain unconstrained. We determined from this dataset that the total respiration quotient, Sigma_-O2/C, and other respiration ratios of POM vary with depth.

[Partition_coefficients_for_COC] - Partition coefficients of the radionuclide into colloidal organic matter from seawater of the west Pacific Ocean and the northern Gulf of Mexico (Biopolymers as carrier phases for selected natural radionuclides (of Th, Pa, Pb, Po, Be) in diatoms and coccolithophores)

To study the binding mechanisms of radionuclides to organic moieties in colloidal organic matter (COM),marine colloids (1 kDa\u20130.2 \u03bcm) were isolated by cross-flow ultrafiltration from seawater of the west Pacific Ocean and the northern Gulf of Mexico. For the same purpose, exopolymeric substances (EPS) produced by laboratory cultured diatoms were collected as well. In our study areas, colloidal organic carbon (COC) concentrations ranged from 6.5 to 202 \u03bcg-C/L in the Pacific Ocean, and were 808 \u03bcg-C/L in the Gulf of Mexico. The COM compositions (organic carbon, organic nitrogen, proteins, total hydrolysable amino acids, total polysaccharides, uronic acids, hydroxamate siderophores, hydroquinone) were quantified to examine the relationships between partition coefficients (Kc) of five different radionuclides, 234Th, 233Pa, 210Pb, 210Po and 7Be, and concentration ratios to COC of individual chelating biomolecules that could potentially act as a chelating moiety. The range of partition coefficients (Kc, reported as logKc) of radionuclides between water and the different colloidal materials was 5.12 to 5.85 for 234Th, 5.19 to 6.01 for 233Pa, 4.21 to 4.85 for 210Pb, 4.87 to 5.68 for 210Po, and 4.49 to 4.92 for 7Be, similar to values previously reported for lab and field determinations under different particle concentrations. While any relationship obtained between Kc and abundance of specific moieties could not be taken as proving the existence of colloidal organic binding ligands for the different radionuclides, it could suggest possible organic moieties involved in the scavenging of these natural radionuclides. Together with results from isoelectric focusing of radiolabeled COM, we conclude that binding to different biomolecules is nuclide-specific, with colloidal hydroxamate siderophoric moieties being important for the binding of Th and Pa radionuclides. Hydroquinones/ quinone (HQ/Q) facilitated redox and chelation reactions seem to be involved in the binding of Pa and Be. However, the actual mechanisms are not clear. Individual amino acids, proteins, total polysaccharides and uronic acids did not yield significant relationships with logKc values of the different radionuclides. Nonetheless, our results provide new insights into the relative importance of different potential ligand moieties in COM in the binding and possible scavenging of specific radionuclides in the ocean.

[PcaFV Prevalence] - Prevalence of PcaFV in Apostichopus californicus specimens collected in Southeast Alaska from Jun to Nov 2021 (Exploring the role of boundary layer microbial remineralization in flavivirus-host dynamics)

Understanding the prevalence and load of aquatic invertebrate flaviviruses is essential to estimating risk to fisheries. We surveyed the prevalence of the Apostichopus californicus (urn:lsid:marinespecies.org:taxname:529363) associated flavivirus (PcaFV) using two approaches: Loop-mediated isothermal amplification (LAMP) and quantitative reverse transcriptase PCR. We targeted this survey around two populations of A. californicus: specimens collected from Sitka Sound, Sitka, Alaska (Baranhof Island) and at undisclosed locations in the Ketchikan sea cucumber commercial fishery. We found that LAMP detected PcaFV in 21 % of tested specimens, and qRT-PCR in 88% of tested specimens. The mean load of PcaFV in copies per ng RNA extracted was significantly higher in specimens that were positive by LAMP compared to those in which LAMP did not detect PcaFV. This dataset contains PcaFV prevalence determined by RT-LAMP and qRT-PCR, as well as associated collection metadata.

[Peptidase and glucosidase activities from mesocosm and bulk water incubations.] - Peptidase and glucosidase activities from mesocosm and bulk water incubations from waters taken aboard the R/V Endeavor in the Western North Atlantic during the research cruise EN683 in May and June, 2022. (Substrate structural complexity and abundance control distinct mechanisms of microbially-driven carbon cycling in the ocean)

This dataset includes the measurements of leucine aminopeptidase, glucosidase, and endo-acting (mid-chain cleaving) peptidase activities from bulk and mesocosm incubations from waters taken aboard the R/V Endeavor in the Western North Atlantic during the research cruise EN683 (2022-05-24 to 2022-06-12). Waters for bulk incubation were taken at three sites and various depths, mesocosm incubations were taken at two sites and two depths.

This research tested the hypothesis that the mechanism of polysaccharide processing is related to the cost to a cell of producing the enzymes required for its hydrolysis, and the probability that a cell will receive sufficient return on investment for producing the enzymes. Our conceptual model suggests that external (extracellular) hydrolysis is favored when organic matter is abundant, or when enzyme production costs can be shared (e.g., on particles, in biofilms); selfish uptake (hydrolysis without production of low molecular weight products in the environment) would be a better strategy when high molecular weight (HMW) organic matter is scarce, and particularly when the HMW organic matter is very complex.

Seawater was sampled from four depths at our initial station, and the deep chlorophyll maximum and bottom water from two subsequent stations differing in typical extent of primary productivity.

We incubated mesocosms of seawater from the deep chlorophyll maximum and from bottom water from two stations differing in typical extent of primary productivity. We changed organic matter availability by adding to three mesocosms high molecular weight organic matter (dissolved and particulate) from diatoms, three mesocosms received an addition of the polysaccharide fucoidan, and three mesocosms were amended with the polysaccharide arabinogalactan. One mesocosm from each depth and station was left unamended.

These data help test this model because they provide information about the activities of exo-acting glucosidases and an exo-acting peptidase, plus endo-acting peptidases, all of which are used to hydrolyze high molecular weight organic matter. Activities of these enzymes differed by station as well as by depth

Despite growing interest of eco-evolutionary dynamics, there have been few experiments that test the importance of these feedbacks in natural ecosystems at the community level. A selection experiment on intra-population variation in dogwhelk (Nucella canaliculata) drilling was performed in the laboratory. Dogwhelks were given one of four early-life diet treatments (thin-shelled Mytilus trossulus mussels, two treatments of M. californianus from two populations known to differ in shell thickness, and acorn barnacles) for the first 3 months of life. Surviving adult dogwhelks were outplanted to field cages at Bodega Marine Reserve to test the ecological consequences of divergent phenotypes. Mussel bed succession was quantified by percent cover of sessile organisms in the plots over the course of approximately one year.

[percent_activity] - Percent activity of organic fractions from diatoms that bind with radionuclide (Biopolymers as carrier phases for selected natural radionuclides (of Th, Pa, Pb, Po, Be) in diatoms and coccolithophores)

Percent amount of organic fractions from diatoms that bind with radionuclide. In order to investigate the importance of biogenic silica associated biopolymers on the scavenging of radionuclides, the diatom Phaeodactylum tricornutum was incubated together with the radionuclides 234Th, 233Pa, 210Pb, and 7Be during their growth phase. Normalized affinity coefficients were determined for the radionuclides bound with different organic compound classes (i.e., proteins, total carbohydrates, uronic acids) in extracellular (nonattached and attached exopolymeric substances), intracellular (ethylene diamine tetraacetic acid and sodium dodecyl sulfate extractable), and frustule embedded biopolymeric fractions (BF). Results indicated that radionuclides were mostly concentrated in frustule BF. Among three measured organic components, Uronic acids showed the strongest affinities to all tested radionuclides. Confirmed by spectrophotometry and two-dimensional heteronuclear single quantum coherence-nuclear magnetic resonance analyses, the frustule BF were mainly composed of carboxyl-rich, aliphatic-phosphoproteins, which were likely responsible for the strong binding of many of the radionuclides. Results from this study provide evidence for selective absorption of radionuclides with different kinds of diatom-associated biopolymers acting in concert rather than as a single compound. This clearly indicates the importance of these diatom-related biopolymers, especially frustule biopolymers, in the scavenging and fractionation of radionuclides used as particle tracers in the ocean.

[Performance of coral and sea anemone early life stages under normoxic and hypoxic conditions] - Performance of coral and sea anemone early life stages under normoxic and hypoxic conditions from lab and field experiments performed in Pennsylvania (USA) and Bermuda in 2023-2024 (CAREER: Helping or hindering? Determining the influence of repetitive marine heatwaves on acclimatization of reef-building corals across biological scales)

This dataset arose from a project in which we investigated how hypoxia influences coral and sea anemone early life stages by comparing hypoxia responses across larvae and juveniles of three cnidarian species representing a range of life histories: the reef-building coral Galaxea fascicularis, a broadcast spawner with horizontal transmission of endosymbiotic algae (family Symbiodiniaceae); the reef-building coral Porites astreoides, a brooder with vertical endosymbiont transmission; and the estuarine sea anemone Nematostella vectensis, a non-symbiotic broadcast spawner. Specifically, larvae were exposed to normoxic (i.e., controls) or hypoxic (dissolved oxygen < 2 mg L−1 for 6 h) conditions before being cultured (under normoxia) through the juvenile stage. Data pertaining to organismal performance—including size, ash-free dry weight, protein content, chlorophyll content, symbiont density, photosynthesis and respiration rates, photochemical yield, heat tolerance (survival and Fv/Fm), settlement rate, and swimming behavior—were collected at several time points alongside environmental variables such as temperature, salinity, and dissolved oxygen concentration.

[Peroxide quantification in T. testudinum tissue] - Peroxide quantification in Thalassia testudinum tissue and response to pathogenic Labyrinthula in seagrass collected February 2024 in Tampa Bay, Florida (Collaborative Research: VIDA Seagrass: Viral Infection Dynamics Among Seagrass)

This dataset presents results of peroxide assays and concentrations of hydrogen peroxide from seagrass tissue. While seagrass serve as a vital foundation species in many coastal ecosystems, investigations of marine host-pathogen interactions continue to be underexplored and provide insights into the biological factors leading to seagrass die-offs. Infection of the marine subtropical seagrass Thalassia testudinum (Banks ex König) by pathogenic Labyrinthula sp. was found to induce alterations to the host's oxidative metabolism over the early stages of infection (monitored over a 72-hr time course). In planta hydrogen peroxide levels provided supporting evidence of a coordinated hypersensitive response in the host plant following infection by the etiological agent of seagrass wasting disease, pathogenic Labyrinthula sp.

[Physicochemical Experimental Data and PcaFV Loads in Experiment] - Dynamics of the Apostichopus californicus-associated flavivirus under suboxic conditions and organic matter amendment in mesocosm experiment (Exploring the role of boundary layer microbial remineralization in flavivirus-host dynamics)

Flaviviruses cause some of the most detrimental vertebrate diseases, yet little is known of their impacts on invertebrates. Microbial activities at the animal-water interface are hypothesized to influence viral replication and possibly contribute to pathology of echinoderm wasting diseases due to hypoxic stress. We assessed the impacts of enhanced microbial production and suboxic stress on Apostichopus californicus (urn:lsid:marinespecies.org:taxname:529363) associated flavivirus (PcaFV) load in a mesocosm experiment. Organic matter amendment and suboxic stress resulted in lower PcaFV load, which also correlated negatively with animal mass loss and microbial activity at the animal-water interface. These data suggest that PcaFV replication and persistence was best supported in healthier specimens. Our results do not support the hypothesis that suboxic stress or microbial activity promote PcaFV replication, but rather that PcaFV appears to be a neutral or beneficial symbiont of Apostichopus californicus. This primary dataset contains per-specimen measurements including experimental treatments, microbial productivity (animal surface and mesocosm water), body wall lipid/protein content, animal mass loss, tissue-specific PcaFV viral loads at initial and final timepoints, and collection metadata. The supplemental file provides time-series measurements of dissolved oxygen and temperature in mesocosms, indexed by tank number, treatment, and timestamp.

[Physiology of Montipora capitata and Porites compressa in response to marine heatwaves] - Physiology of Montipora capitata and Porites compressa from October 2019 to September 2022 in response to marine heatwaves (2015 and 2019) in Hawaiʻi (RAPID: Collaborative Research: Disentangling the effects of heat stress versus bleaching phenotype on coral performance)

Increasingly frequent marine heatwaves are devastating coral reefs. Corals that survive these extreme events must rapidly recover if they are to withstand subsequent events, and long-term survival in the face of rising ocean temperatures may hinge on recovery capacity and acclimatory gains in heat tolerance over an individual's lifespan. To better understand coral recovery trajectories in the face of successive marine heatwaves, we monitored the responses of bleaching-susceptible and bleaching-resistant individuals of two dominant coral species in Hawaiʻi, Montipora capitata and Porites compressa, over a decade that included three marine heatwaves. This dataset includes all of the physiological data for both species from October 2019 to September 2022.

The unicellular cyanobacterium Synechococcus is one of the most important primary producers in the ocean, and its growth and distribution are regionally limited by iron (Fe) concentration and temperature. However, the potential interactions between Fe availability and ocean warming in Synechococcus remain largely unexplored. We cultivated coastal (XM24) and oceanic (YX04-1) Synechococcus isolates from South China Sea under a matrix of two Fe concentrations (2 nM, 250 nM) and temperatures (24°C, 27°C) to investigate their physiological and transcriptomic responses. This dataset includes the sample identifier, strain information, iron and temperature treatment information, normalized iron quotas, carbon fixation rates, particulate organic nitrogen, and particulate organic carbon measurements.

These data include division rates, grazing rates, and accumulation rates from dilution experiments conducted on cruises aboard the R/V Robert Gordon Sproul (SP2319, SP2320) between dates 2023-07-28 and 2023-08-19 along the Southern California coast. Dilution experiments were used to assess phytoplankton growth and microzooplankton grazing rates.

Deposition of wildfire ash on the ocean can fertilize microbial production but also has the potential to inhibit microbial growth due to heavy metal toxicity. The data collected from these field experiments can contribute to elevating understanding of wildfire-driven material transfer from the terrestrial system to the ocean and its impact on carbon and energy flow in marine food webs. These data were collected by Dr. Nicholas Baetge, Dr. Jason Graff, Dr. Allen Milligan, Brian Ver Wey, and Parker Hansen of Oregon State University.

[Phytoplankton Growth Acclimation] - Growth rates and equivalent spherical diameters of Heterosigma akashiwo after temperature transition (Quantifying Temperature Dependence In Growth & Grazing Rates of Planktonic Herbivores)

Quantifying phytoplankton growth as a function of environmental conditions such as temperature is critical for understanding and predicting production in the ocean. Typically, thermal response is described as the steady state growth rates under static conditions. However, here, with a clonal culture of Heterosigma akashiwo, temperature was manipulated in the laboratory with the goal of describing how growth rates may change over time through the acclimation process. Growth rates and equivalent spherical diameter of Heterosigma akashiwo after temperature transition are reported.

[Phytoplankton size over temperature range] - Equivalent spherical diameter of Heterosigma akashiwo grown at different temperatures (Quantifying Temperature Dependence In Growth & Grazing Rates of Planktonic Herbivores)

A key component of the effects of temperature on growth and production of phytoplankton is not only through changes in numerical abundance, but also biomass and proxies for biomass such as biovolume. To understand how temperature affected size and biovolumetric growth, repeated measurements of the mean size feature, equivalent spherical diameter (ESD), were recorded for each experimental replicate culture of Heterosigma akashiwo across a broad range of temperature treatments. These data were collected as part of the experiment designed to study the effect of changing temperature on phytoplankton growth rates.

[phytoplankton taxonomy] - Time-Series of Phytoplankton Taxonomy and Density collected by the CARIACO Ocean Time-Series Project from November 1995 to January 2017 (CARIACO Ocean Time-Series Program)

The CARIACO Ocean Time-Series Program (formerly known as CArbon Retention In A Colored Ocean) started on November 1995 (CAR-001) and ended on January 2017 (CAR-232). Monthly cruises were conducted to the CARIACO station (10.50\u00b0 N, 64.67\u00b0 W) onboard the R/V Hermano Gin\u00e9s of the Fundaci\u00f3n La Salle de Ciencias Naturales de Venezuela. The program studied the relationship between surface primary production, physical forcing variables like the wind, and the settling flux of particulate carbon in the Cariaco Basin. This depression, located on the continental shelf of Venezuela, shows marked seasonal and interannual variation in hydrographic properties and primary production (carbon fixation rates by photosynthesis of planktonic algae).\r\n\r\nOne of the monthly measurements taken by the program was water sampling at different depths for phytoplankton taxonomy (occurrence and density). Those water samples were collected with Niskin bottles during the first CTD Cast of the morning at 1, 7, 25, 35, 75, and 100 m depth. Phytoplankton taxonomy and density was determined at each depth at the level of species or genera. Values of zero are real and denote that a specific species was not found at that cruise/depth.

Picoeukaryotic phytoplankton observations from available public repositories and primary sources. Picoeukaryotic phytoplankton are defined as red fluorescent cells larger than Prochlorococcus and less than 2-3 \u00b5m in cell diameter. We only considered cell counts by flow cytometry. Samples covered a latitudinal range from 71.4\u02daN to 66.1\u02daS up to 400 m depth. Ancillary temperature and nitrate records were available for all but 2,334 and 6,530 observations, respectively, which we complemented with 1\u00b0 monthly depth-dependent averages from the World Ocean Atlas (www.nodc.noaa.gov). To avoid analytical issues with detection limits, we imposed a minimum nitrate concentration of 0.01 \u03bcM. We calculated surface PAR (8 d averaged, 0.047\u00b0 grid cell) using SeaWiFS and MODIS observations. Downward PAR was estimated using the attenuation coefficient K\u2084\u2089\u2080 from SeaWiFS and MODIS (https://oceancolor.gsfc.nasa.gov) and corrected for chlorophyll a\u00b3\u2070, and a minimum of 10\u207b\u00b3 E/m\u00b2d was imposed.

These data represent measurements of individual sinking particle types—specifically fecal aggregates, phytodetrital aggregates, euphausiid and other crustacean fecal pellets, and debris—collected from the Bermuda Atlantic Time-series Study (BATS) site. Sampling occurred during six time points: July 2021, November 2021, March 2022, July 2022, November 2022, and March 2023. Particle interceptor traps (PITs) were deployed at depths of 150 m, 200 m, and 300 m, each equipped with three gel-filled collection cups to preserve particle morphology. The collected particles were analyzed to quantify area and biovolume for each particle type, contributing to a better understanding of the composition and flux of sinking material in the mesopelagic zone.
The data were collected aboard the R/V Atlantic Explorer through the collaborative efforts of the laboratories of Dr. Susanne Neuer, Dr. Amy Maas, and Dr. Leocadio Blanco-Bercial, affiliated with Arizona State University and the Bermuda Institute of Ocean Sciences. These measurements support research into particle-mediated carbon flux and the biological carbon pump, and are intended for use by scientists studying marine biogeochemistry, particle dynamics, and oceanic carbon cycling.

[Planktic foraminifera assemblages MAZ-1E-04] - Planktic foraminifera assemblages in the eastern Pacific during the last deglaciation determined from core MAZ-1E-04 collected on cruise MAZ-I aboard the R/V El Puma in April 2015 (Glacial-Interglacial Changes in Oxygen Minimum Zones Using Deep-Dwelling, Low-Oxygen Planktic Foraminifera)

The structure and drivers of oxygen minimum zone (OMZ) evolution in the Eastern Tropical North Pacific (ETNP) are investigated from ~20.7-10 ka using planktic foraminiferal assemblages alongside multiple other proxies from core MAZ-1E-04 (22°54.29'N, 106°54.59'W; 1463 m depth). Understanding how OMZ vertical structure changed during past glacial/interglacial cycles will help elucidate the drivers and patterns of OMZ expansion/contraction on longer timescales.

Planktic foraminifera assemblage counts from core MAZ-1E-04, collected on cruise MAZ-I aboard the R/V El Puma in April 2015, are used here to explore any composition shifts driven by environmental changes. Universidad Nacional Autónoma de México financed ship time and M. Alejandro Rodríguez Ramírez directed the oceanographic campaign to retrieve the core.
