[tidepool ammonium and mussels] - Ammonium in tidepools with and without mussels from Cape Flattery, WA from 2010-2011 (Regenerated Nitrogen project) (The Role of Regenerated Nitrogen for Rocky Shore Productivity)

Summary:
We evaluated the role of mussels by adding 15N-labeled NH4+ to an assemblage
of tidepools where they were either present at natural abundance levels, or
absent through manual removal. \u00a0The role of phototrophs was separately
examined by conducting these experiments both during the day and at night.
\u00a0The tidal height of pools varied between 1.2 to 1.5 m above Mean Lower
Low Water (MLLW). Tidepools were thus isolated from each other as well as the
nearshore environment during the low tide period when experiments were
conducted. Each experiment included 4 to 5 mussel removal (MR) tidepools
(since 2002) and 4 to 5 mussel control (MC) tidepools with natural mussel
densities. \u00a0In June 2010, we performed daytime NH4+ tracer experiments
and in August 2010 nighttime experiments using the same tidepools. The
following year (July 2011) these experiments were repeated with the addition
of bottle incubations (see below) to evaluate the effects of suspended
tidepool components and extended sampling for 6 days after the initial 15N
addition to test for long-term retention of NH4+. \u00a0During the 2011
experiments, unforeseen rain reduced the salinity in some pools by up to 51%,
and we have attempted to correct for the expected dilution of NH4+ in our
tidepool rate calculations.

Because isotope enrichment levels were relatively low, we used the
conventional delta notation instead of atom% to describe variations in 15N
enrichment (where delta-15NH4+ = {(15N:14N sample \u00f7 15N:14N standard)
-1}\u00d71000\u2030, where the standard is atmospheric N2. \u00a0Tracer
labeled ammonium chloride (15NH4Cl) was added to the pools to approximate a
1000\u2030 enrichment in 2010 (doubling the 15N-NH4+ concentration) and a
2000\u2030 enrichment in 2011(tripling the 15N-NH4+ concentration). 15N
natural abundance is only 0.365% and these tracer additions thus had a
negligible effect on the overall NH4+ concentrations increasing them by only
~0.4% and ~0.8%, respectively. Tidepool volumes were estimated
spectrophotometrically using varying concentrations of food dye (Pfister
1995). Together with estimates of NH4+ concentration (from 2009 data), we
estimated the tracer addition required to achieve the targeted 15N
enrichments. However, the actual initial enrichments varied substantially,
684.4 - 2406.4\u2030 in 2010 and 781.4 - 3880.2\u2030 in 2011, likely due to
error in tidepool volume estimation and natural variations in initial NH4+
concentrations. Fortunately, we sampled immediately following each tracer
addition allowing for the determination of the true initial 15N enrichment.
\u00a0

Prior to tracer addition at ebb tide, 100 mL of tidepool water was syringe-
filtered (Whatman GF/F) into separate HDPE bottles for natural abundance
15NH4+ and concentration determination. \u00a0To each pool, tracer 15NH4+ was
then added and distributed by stirring with a stick. Water samples were
immediately collected for measuring initial 15N enrichment and subsequently at
2, 4, and 6 hour intervals to determine isotope and concentration time
courses. All water samples were frozen until analysis. Tidepool oxygen, pH,
and temperature (Hach HQ4D) were also collected at ~ 2 h intervals throughout
the experiment.

In 2011 we also assessed the contribution of the suspended microbial community
to NH4+ cycling by enclosing tidepool water in a 250 mL transparent
polycarbonate incubation bottle. Following tracer addition, the bottle was
filled, then left to float in the tidepool for the duration of the experiment.
Samples from bottles were filtered as described both immediately after
containment and at the end of the experiment (~6 h later).

We assessed macroalgal contribution to NH4+ removal by transplanting two
tidepool-dwelling algae species. \u00a0Prionitis sternbergii were sampled 2
weeks prior to the experiment for baseline natural abundance 15N values and
transplanted into the pools with Z-Spar Epoxy (Pfister 2007). On the day of
the experiment, the red-alga, Corallina vancouveriensis from a single source
patch, was also sampled for 15N natural abundance, inserted into pieces of
Styrofoam, and floated in each pool.

At the end of each experiment (~6 h sampling point), we sampled tidepool
particulate organic material (POM) by filtering through combusted GF/F filters
until they clogged (~ 600 mL), comparing these samples with POM similarly
sampled from the immediate nearshore. \u00a0Floating Corallina spp. samples
were collected into clean Eppendorf tubes, and similar sized pieces of
Prionitis spp. were collected from each pool into clean foil packets.\u00a0
 We evaluated the extent of longer-term 15N tracer retention in 2011 by
sampling tidepool water, POM and transplanted Prionitis 1, 3, and 6 days
following tracer addition. We sampled at ebb tide and at again at slack water
just prior to high tide on the first day after tracer addition (that is, 24 h
later) and at slack water prior to high tide on Day 3 and 6.\u00a0

[Time to development larval purple urchins] - Time to developmental stage across temperature and food experiments in the larval purple sea urchin, Strongylocentrotus purpuratus (Collaborative Research: The effects of marine heatwaves on reproduction, larval transport and recruitment in sea urchin metapopulations)

Summary:
Trends in development time and time to metamorphic competency across temperature and food availability treatments were measured in Strongylocentrotus purpuratus larvae. Effects of temperature and food availability were tested using a 6 x 4 factorial experimental design with six temperature treatments (10, 12, 14, 16, 18, 20°C) and four concentrations of Rhodomonas sp. microalgae (500, 2500, 5000, 10,000 cells mL-1) for a total of 24 treatment combinations. Developmental stage was determined in>50% individuals were of a certainstage and metamorphic competency was determined when >50% of larvae exhibited tube feet and adhered to the bottle. Time to metamorphic competency decreased exponentially with temperature with larvae at 10°C reaching competency in 61 days, larvae at 12ºC in 33 days, larvae at 14ºC in 29 days, larvae at 16ºC in 25 days, larvae at 18ºC in 22 days, and larvae at 20ºC in 21 days.

[Tissue data from Keister et al. 2023] - Comparative analysis of tissue biomass and energy reserves of six coral species from nearshore and offshore reefs in Palau, Micronesia during March 2017 (Collaborative Research: Stability, flexibility, and functionality of thermally tolerant coral symbioses)

Summary:
The nearshore reef habitats in Palau, Micronesia, serve as a representation of the challenges that coral populations may face in a future with warmer and more acidic oceans. Interestingly, corals inhabiting these nearshore habitats demonstrate a greater ability to withstand and recover from episodes of thermal stress compared to their offshore counterparts. In order to investigate the underlying physiological mechanisms behind this tolerance, we conducted a comparative analysis of six coral species found in both offshore and nearshore environments. Specifically, we examined parameters such as tissue biomass (ash-free dry weight cm−2), energy reserves (including protein, total lipid, and carbohydrate content), as well as several crucial lipid classes.

[TMs and Nuts from EXPORTS NA Incubations] - Dissolved trace metal and macronutrient concentration data from incubation experiments conducted during the May 2021 EXPORTS North Atlantic cruise (DY131) (Collaborative Research: Diatoms, Food Webs and Carbon Export - Leveraging NASA EXPORTS to Test the Role of Diatom Physiology in the Biological Carbon Pump)

Summary:
This dataset includes trace metal (iron, manganese, cobalt, nickel, copper, zinc, cadmium, lead) and macronutrient (nitrate+nitrite, nitrite, phosphate, silicic acid) concentration data from incubation experiments conducted on board the RRS Discovery during the EXPORTS North Atlantic campaign at the Porcupine Abyssal Plain-Sustained Observatory (PAP-SO) site (DY131). In these experiments, additions of macronutrients (N, P, Si) and Fe were used to assess the level of Si, N, and Fe stress being experienced by the phytoplankton and to contextualize taxa-specific metatranscriptome responses for resolving gene expression profiles in the in-situ communities.

This research project focuses on the vertical export of the carbon associated with a major group of phytoplankton, the diatoms in the North Atlantic near the Porcupine Abyssal Plain. The major objective is to understand how diatom community composition and the prevailing nutrient conditions create taxonomic differences in metabolic state that combine to direct diatom taxa to different carbon export pathways. The focus is on diatoms, given their large contribution to global marine primary productivity and carbon export which translates into a significant contribution to the biogeochemical cycling of carbon (C), nitrogen (N), phosphorus (P), iron (Fe) and silicon (Si). It is hypothesized that the type and degree of diatom physiological stress are vital aspects of ecosystem state that drive export. To test this hypothesis, combined investigator expertise in phytoplankton physiology, genomics, and trace element chemistry is used to assess the rates of nutrient use and the genetic composition and response of diatom communities, with measurements of silicon and iron stress to evaluate stress as a predictor of the path of diatom carbon export. The EXPORTS field campaign in the North Atlantic sampled a retentive eddy over nearly a month in May 2021, which coincided with the decline of the North Atlantic Spring Bloom.

[Total dissolved Cr concentration and isotopic composition in the ETNP from RR1804-05 and KM1919-20] - Total dissolved chromium (Cr) concentration and isotopic composition in the Eastern Tropical North Pacific from samples collected on R/V Roger Revelle and R/V Kilo Moana in April-May 2018 and Sept-Oct 2019 (Cr Isotope Oceanography of the Eastern Tropical North Pacific Ocean)

Summary:
Understanding the cycling of chromium (Cr) and how chromium stable isotopes (δ53Cr) are altered in response to different processes in the modern ocean is important in our interpretation of marine sedimentary δ53Cr records, a promising redox proxy. Therefore, it is crucial to investigate the geochemical processes of Cr in reducing environments such as oxygen deficient zones (ODZs). In this study, we investigated the cycling of Cr in the Eastern Tropical North Pacific (ETNP) ODZ by analyzing the [Cr] and δ53Cr of total dissolved Cr and Cr(III). Our Cr(III) data at two inshore stations shows profile features and Cr reduction isotopic fractionation factor (-1.5‰) similar to an offshore station in a previous study. We also observed significant Cr scavenging signals in the upper 1000 meters (m) throughout the ODZ with an inshore-offshore variability in its magnitude. Specifically, anoxic bottom waters on the continental slope see the greatest Cr scavenging with heaviest δ53Cr (+1.85‰). Our estimates of the scavenged Cr isotopic composition are within error of the anoxic and euxinic marine sedimentary δ53Cr. This implies that the vertical transport of Cr to the seafloor and subsequent diagenesis may not generate significant isotopic fractionation for Cr. This is the first thorough investigation into the Cr cycling in the ETNP ODZ and demonstrated promising usage of marine sedimentary δ53Cr as a redox proxy for ancient oceans.

In the ODZ, oxygen is consumed by degrading sinking particles and reaches extremely low levels (too low to support aerobic life) from 100m to 800m depth. However, microbes that can use other oxidants such as nitrate to metabolize organic carbon live there, and we showed that they also convert soluble anionic chromate Cr(VI) to cationic Cr(III), about half of which is scavenged onto sinking particles and removed to the seafloor. This reduction is accompanied by preferential reduction of light Cr isotopes, so the Cr(III) is 1.3‰ lighter than the source Cr(VI). The removal of part of this light Cr(III) by scavenging leaves the residual total Cr heavier than the source Cr. The analyzed samples listed here were chosen to be from the center and margins of the ETNP ODZ and over extremely reducing continental margin sediments.

[Tracer data] - Nutrient transfer experiments with host coral and symbionts under varying environmental conditions in March 2014 and March 2015 (Collaborative Research: Stability, flexibility, and functionality of thermally tolerant coral symbioses)

Summary:
Symbiotic mutualisms are essential to ecosystems and numerous species across the tree of life. For reef-building corals, the benefits of their association with endosymbiotic dinoflagellates differ within and across taxa, and nutrient exchange between these partners is influenced by environmental conditions. Furthermore, it is widely assumed that corals associated with symbionts in the genus Durusdinium tolerate high thermal stress at the expense of lower nutrient exchange to support coral growth. We traced both inorganic carbon (H13CO3–) and nitrate (15NO3–) uptake by divergent symbiont species and quantified nutrient transfer to the host coral under normal temperatures as well as in colonies exposed to high thermal stress. Colonies representative of diverse coral taxa associated with Durusdinium trenchii or Cladocopium spp. exhibited similar nutrient exchange under ambient conditions. In contrast, heat-exposed colonies with D. trenchii experienced less physiological stress than conspecifics with Cladocopium spp. while high carbon assimilation and host transfer was maintained. This discovery is different from the prevailing notion that these mutualisms inevitably suffer trade-offs in physiological performance. These findings emphasize that certain host-symbiont combinations adapted to high temperature equatorial environments; and why their increase in prevalence is likely important to the future productivity and stability of coral reef ecosystems.

[Trematode Parasite COI Sequences] - COI mtDNA sequences for trematodes from fish collections across the Northern Line Islands and French Polynesia archipelagos collected between 2009 and 2023 (Collaborative Research: Decomposing the effects of diversity on the abundance of marine parasites)

Summary:
The loss of biological diversity is considered one of the principal environmental challenges of the 21st century, and there are hints that this massive reorganization of food webs could affect how parasites are transmitted among hosts. Parasites are often hidden and can be easy to overlook, but they are ecologically important and ubiquitous - so it is important to understand whether we should expect more or fewer of them as biodiversity disappears. Does biodiversity loss increase the abundance of parasites by eroding natural "checks and balances" on transmission? Or does it decrease parasite abundance by removing the free-living biodiversity on which parasites depend? Answers to these questions are urgently needed if we are to mitigate or prevent an uptick in parasite transmission for ecosystems experiencing biodiversity loss.

In a joint collaborative research project among the University of Washington, Scripps Institution of Oceanography at UC San Diego, and California State University Monterey Bay, we created a parasite dataset of unprecedented size and taxonomic resolution. We sampled parasites of coral reef fishes from 19 replicate islands in the central equatorial Pacific to study how biodiversity and parasite burden covary.

This data set contains COI mtDNA sequence accession numbers, collection locations, and life stages for trematodes from the family Microscaphidiidae and Paramphistomatidae from fish collections across the Northern Line Islands and French Polynesia archipelagos collected between 2009 and 2023. Specifically this data set represents 87 Microscaphidiidae samples from the Northern Line Islands and 132 Paramphistomatidae from French Polynesia.

Summary:
The \u201cdissolution\u201d method to measure N2 fixation rates with 15N2 gas tracer involves the preparation of 15N2-enriched water that is then added to each incubation bottle. Investigators typically measure the 15N2 atom% of the 15N2-enriched inoculum by MIMS, and extrapolate the 15N2 atom% in the incubations based on the inoculum value. Here, we demonstrate that such extrapolation yields inaccurate estimates of the 15N2 atom% of incubations. The latter should be measured directly.

[Trichodesmium AHL metatranscriptomes_AE1409] - Trichodesmium AHL amendment metatranscriptomic reads accessions and metadata (Dissolved Phosphorus Processing by Trichodesmium Consortia: Quantitative Partitioning, Role of Microbial Coordination, and Impact on Nitrogen Fixation)

Summary:
Trichodesmium is a marine, diazotrophic cyanobacterium that plays a central role in the biogeochemical cycling of carbon and nitrogen. Colonies ubiquitously co-occur with a diverse microbiome of heterotrophic bacteria. Here we show that manipulation of the microbiome with quorum sensing acyl homoserine lactone (AHL) molecules significantly modulated rates of N2 fixation by Trichodesmium collected from the western North Atlantic, with both positive and negative effects of varied magnitude. Changes in Trichodesmium N2 fixation did not clearly correlate with changes in microbiome composition or geochemical patterns. Metatranscriptome sequencing revealed significant changes in the relative abundance of microbiome transcripts encoding metabolic functions consistent with quorum sensing responses in model bacteria. There was little overlap in specific microbiome transcriptional responses to AHL addition between stations, and this variability in microbiome gene expression may underpin the heterogeneous changes in Trichodesmium N2 fixation. These data suggest the microbiome could play a large and previously overlooked role in modulating Trichodesmium N2 fixation. This metadata form describes the metatranscriptomic sequencing reads that were used in the study.

[Triple oxygen isotopes of respiration and photo-oxidation of DOC] - Triple oxygen isotopes of respiration and photo-oxidation of DOC (Clumped Oxygen Isotope Signature of Marine Dissolved Oxygen)

Summary:
The biogeochemical fluxes that cycle oxygen (O2) play a critical role in regulating Earth's climate and habitability. Triple-oxygen isotope (TOI) compositions of marine dissolved O2 are considered a robust tool for tracing oxygen cycling and quantifying gross photosynthetic O2 production. This method assumes that photosynthesis, microbial respiration, and gas exchange with the atmosphere are the primary influences on dissolved O2 content, and that they have predictable, fixed isotope effects. Despite its widespread use, there are major elements of this approach that remain uncharacterized, including the TOI dynamics of respiration by marine heterotrophic bacteria and abiotic O2 sinks such as the photochemical oxidation of dissolved organic carbon (DOC). Here, we report the TOI fractionation for O2 utilization by two model marine heterotrophs (Vibrio harveyi and Ruegeria pomeroyi DSS-3) and by abiotic photo-oxidation of representative terrestrial and coastal marine DOC. These data are described further in the related publication, Sutherland et al., 2022 (doi: 10.1093/pnasnexus/pgac233).

Summary:
These data include profiles of turbulence dissipation rate obtained from a Rockland Scientific VMP-250 deployed during a cruise on the Northeast Continental Shelf to study particle disaggregation. One cruise was completed aboard the R/V Hugh R. Sharp from 2022-04-21 through 2022-05-02 (HRS22-04), which visited a variety of stations and hydrodynamic environments associated with the Northeast Continental Shelf of the United States. Cruise stations where dissipation rate profiles were obtained ranged from Georges Bank and the Great South Channel near the Gulf of Maine, and Hudson Canyon near New York. These data were collected as part of a study to clarify the importance of hydrodynamic forces on the cohesion, aggregation, and breakup of marine particles. These data were collected by Dr. Matthew Rau (chief-sci) of the George Washington University.

[Underway Data] - Underway data from estuary transects in Coastal Gulf of Maine (Pleasant, Maine; St. John, New Brunswick) in May and October of 2018 and 2019 (Collaborative Research: Organic Alkalinity: Impacts of the [OTHER] Alkalinity on Estuary and Coastal Ocean Chemistry)

Summary:
This dataset contains underway data from four organic alkalinity estuary transects, in May and October of 2018 and 2019, completed in the Pleasant (Maine, USA) and St. John (New Brunswick, Canada) estuaries. See "Related Datasets" section for alkalinity data.  Discrete samples were collected at intervals of salinity along each estuary.  An underway measurements system was also operated during each transect.  Discrete samples were analyzed via a number of methods described below.  Underway measurements were collected using the procedures described in Hunt et al. (2013).

Organic alkalinity is a poorly understood component of the estuarine and coastal ocean acid-base system.  This lack of understanding makes assessment of ocean acidification vulnerability and inorganic carbon dynamics more difficult.  However, the methods used to quantify organic alkalinity and its effects on the acid-base system are not standardized.  In this work we examined several approaches for the measurement of organic alkalinity, and their application to inorganic carbon dynamics.

[Vertical profiles] - Vertical profiles and attenuation coefficients during intense blooms in the Lower York River Estuary between August 2021 and September 2022 (Alteration of carbon fluxes by intense phytoplankton blooms in a microtidal estuary)

Summary:
The dinoflagellates Margalefidinium polykrikoides and Alexandrium monilatum form intense summer blooms in the lower York River Estuary (LYRE), typically from late July through mid-September.  While surface concentrations of chlorophyll-a during these blooms are well-documented, we lack information on the vertical distribution of biomass in bloom patches.  Both species are known to vertically migrate and accumulate near the surface at midday.  We also lack direct measurements of light attenuation through intense bloom patches for comparison to attenuation through the background phytoplankton assemblage.  We conducted vertical profiles of water column structure, phytoplankton chlorophyll-a, and irradiance on five dates during these intense summer blooms in the LYRE.  Ten to twelve stations were occupied on each date spanning a wide range of bloom densities, including background stations outside of bloom patches.  Profiles were used to determine the vertical distribution of bloom biomass, while irradiance measurements were used to compute the vertical attenuation coefficient as a function of bloom chlorophyll-a biomass, determined from laboratory extraction of surface samples.

[Virus production at a hydrothermal vent site] - Virus and prokaryote abundances from experiments conducted with samples collected at a hydrothermal vent site by ROV SuBastian during R/V Falkor (too) expedition FKt230627 along the East Pacific Rise in July of 2023 (The Underworld of Hydrothermal Vents)

Summary:
We used the virus-dilution technique to quantify lytic virus production at nine sites across vent, sub-vent, and non-vent habitats along the East Pacific Rise during expedition FKt230627 aboard R/V Falkor(too). This technique leverages the density-dependent nature of viral infection, preventing new infections by dilution. Samples were collected via ROV SuBastian, sequentially filtered to remove larger particles, and concentrated using tangential-flow filtration. Duplicate incubations were set up with prokaryotic concentrate and virus-free water, pressurized to 250 bar, and incubated in the dark at in situ temperatures for 30 hours. Subsamples were taken every six hours for enumeration of prokaryotes and viruses via flow cytometry. Parallel experiments were conducted at surface pressure to assess the impact of pressure on virus production rates. The methodology ensures observed increases in viral abundance are due to pre-existing infections. The experiments were conducted aboard R/V Falkor(too) between 5-22 July 2023 by Tinkara Tinta and Nicole Krause. Prokaryotes and viruses were enumerated flow-cytometrically back in the lab by Christian Winter.
