[Global Seabird Breeding Success] - Annual seabird productivity at breeding colonies around the world from 1964 to 2023 (Stratification Impacts on Seabirds Project) (Global analysis of stratification impacts on seabirds through food resources )

This global dataset on breeding productivity represents a compilation of individual time series from species and sites (seabird breeding colonies) across the world. Each time series was contributed by a Global Seabird Working Group (GSWG) collaborator. It contains the number of offspring produced per nesting female per year, which is a variable measured similarly by researchers. Seabird breeding productivity is typically measured by monitoring individual nest sites through time within each breeding season. Data from multiple females are then averaged to produce estimates of annual productivity for each species at each site, resulting in “species-site” time series. Typically, measurements are made for multiple species at each site, so data are often available for a portion of the full seabird community, including species feeding at different trophic levels and in different parts of the water column. Variance for species-site breeding productivity is estimated as the standard error across years for each time series. Here, there are 202 time series encompassing 87 sites and 73 seabird species.

[Globorotaloides hexagonus trace element ablation profiles] - Globorotaloides hexagonus trace element ablation profiles from samples collected from MOCNESS tows from R/V Sikuliaq cruise SKQ201701S in 2017 (Glacial-Interglacial Changes in Oxygen Minimum Zones Using Deep-Dwelling, Low-Oxygen Planktic Foraminifera)

The planktic foraminifer Globorotaloides hexagonus is found in temperate to tropical oxygen minimum zones (OMZs). Their preferred habitat make G. hexagonus an important species for the development of oxygen-related paleoproxies. Here we report trace-element-to-calcium (TE/Ca) ratios with depth in the shell of G. hexagonus from the Eastern Tropical North Pacific (21 N, 117 W) . Individuals were isolated from a series of Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) tows on the R/V Sikuliaq  in January and February 2017 and represent a wide range of depth habitats and  oxygen concentrations. Oxygen concentration and depth from MOCNESS are provided in the metadata for each sample. Trace elements (Mg, Mn, Zn, Sr, Ba, Ca) were quantified using laser ablation ICP-MS from the outside to the inside of the shell, allowing for a reconstruction of TE/Ca with depth in the shell. MOCNESS data were collected by Dr. Karen Wishner (URI),  ablation data were collected by Dr. Catherine Davis (NCSU) and Dr. Jennifer Fehrenbacher (OSU), and data were prepared by Dr. Shannon Doherty (NCSU and UAF).

[GN01 Dissolved Fe(II)] - Dissolved Fe(II) from the southbound leg of the US GEOTRACES Arctic cruise (HLY1502) on USCGC Healy from August to October 2015 (U.S. Arctic GEOTRACES Study)

Dissolved Fe(II) concentrations were determined using an automated flow injection analysis system (FeLume II Waterville Analytical) employing a luminol chemiluminescence based detection system as described in King et al. (1995) and Heller et al. (2017).\r\n\r\nFrom published and ongoing work in the Peru and Chile oxygen minimum zones an optimized methodology for Fe(II) detection by luminol has been described in Croot et al. (2019). This work details some of the challenges and limitations of using luminol for dFe(II) detection. It should be noted that as Fe(II) is a transient redox species with a short half life in oxygenated seawater that is dependent on dissolved oxygen and pH, it is not possible to archive (preserve) samples for later analysis. Intercalibrations for Fe(II) have yet to be conducted in the context of GEOTRACES studies and should be pursued where logistically possible.

[GN01 Dissolved Methane (CH₄)] - Dissolved methane (CH₄) concentrations from the U.S. GEOTRACES Arctic cruise (HLY1502; GN01) on USCGC Healy from August to October 2015 (U.S. Arctic GEOTRACES Study (GN01))

This dataset reports dissolved methane (CH₄) concentrations from the US GEOTRACES Arctic Expedition on USCGC Healy (GN01, HLY1502) from August to October 2015. Seawater samples were collected using the ODF rosette. Both GEOTRACES samples and GO-SHIP samples from the same cruise were analyzed. Methane was analyzed using cavity ringdown spectroscopy to determine its concentration in an equilibrated headspace. Arctic waters are a possibly significant source of this Greenhouse Gas to the atmosphere and global change is likely exacerbating its release. Methane is also a potentially valuable indicator of interactions with the shelf as well as of river inputs. Dissolved methane concentrations in this section were highest over the continental shelves and slope, which supports our understanding of the major sources of methane (i.e., from microbes in oxygen-limited sediments, from gas seeps, and from gas-hydrates).

[GN01 Silicon Stable Isotopes] - Depth profiles of the isotopic composition (d30Si) of silicon within dissolved silicic acid on the US GEOTRACES Arctic cruise GN01 (HLY1502) from August to October 2015 (U.S. Arctic GEOTRACES Study)

The isotopic composition of dissolved silicon (\u03b430Si) has proven to be a powerful tool to better understand the marine Si cycle. The \u03b430Si of seawater carries information about DSi utilization in surface waters, the subsequent dissolution of sinking biogenic material as well as water mass mixing. This data set supplies information on the spatial distribution of isotopes of Si within water masses in the Arctic Ocean from the Bering Strait to the north pole. Profiles of silicon isotopes within silicic acid, \u03b430Si(OH)4, were obtained at a total of 15 stations on the GEOTRACES GN01 cruise

These data include the stable carbon isotope of dissolved inorganic carbon (δ13C-DIC) collected during the Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) A16N cruise in 2023. The cruise was divided into two legs and all aboard the R/V Ronald H. Brown between dates 2023-03-06 and 2023-05-09 in the North Atlantic Ocean. An automated, efficient, and high-precision method for ship-based δ13C-DIC analysis based on Cavity Ring-Down Spectroscopy (CRDS) was used. Stable isotopes of carbon can be used as a "signature" to identify fossil fuel-derived carbon dioxide in the atmosphere and ocean. These data were collected by Dr. Wei-Jun Cai's group of the University of Delaware.

[GP09 dissolved trace elements] - Dissolved trace elements in profiles and surface waters collected during the Chinese GEOTRACES cruise (GP09) in the tropical northwest Pacific Ocean from April to June 2019 (Dissolved trace elements in the tropical Northwest Pacific Ocean)

This is a study of dissolved trace elements in profiles and surface waters collected during the Spring 2019 Chinese GEOTRACES cruise (GP09) in the tropical northwest Pacific Ocean. GP09 afforded the opportunity to obtain trace element clean water samples (provided by the cruise organizers) from a region that is geologically complex as well as being a meeting place for various ocean currents and water masses. GP09 sampled the southwest corner of the North Pacific subtropical gyre, one of the largest oligotropic ocean regions and arguably the largest continuous ecosystem on Earth. Yet this region has been poorly studied for trace element distributions. We determined dissolved trace element concentrations by using established high-resolution ICP-MS methods.

[GP15 Aerosol Pb and Pb Isotopes Leg 1] - Aerosol lead (Pb) and Pb isotopes from Leg 1 (Seattle, WA to Hilo, HI) of the US GEOTRACES Pacific Meridional Transect (PMT) cruise (GP15, RR1814) on R/V Roger Revelle from September to October 2018 (US GEOTRACES Pacific Meridional Transect (GP15))

Dr. Chris Marsay collected shipboard aerosol samples during the U.S. GEOTRACES GP15 Pacific Meridional Transect cruise on R/V Revelle from October to November 2018 and provided subsamples to Massachusetts Institute of Technology (MIT) for lead (Pb) and Pb isotope analyses. These were carried out by undergraduate student Avery Wang and Research Scientist Jahander Ramezani. The north-south transect shows large Pb concentration and Pb isotope changes. The Pb concentration variability is very similar to the Pb concentrations measured independently by Dr. Marsay. The Pb isotope ratios show a strong Chinese signature in the northern portion of the transect, and ratios more similar to American and Australian signatures further south.

[GP15 delta30Si Leg 1] - Depth profiles of the isotopic composition (δ30Si) of silicon within dissolved silicic acid from samples collected on Leg 1 of the US GEOTRACES Pacific Meridional Transect (PMT) cruise (GP15, RR1814) on R/V Roger Revelle from September to October 2018 (US GEOTRACES Pacific Meridional Transect (GP15))

The isotopic composition of dissolved silicon (δ30Si) has proven to be a powerful tool to better understand the marine Si cycle. The δ30Si of seawater carries information about dissolved silicon utilization in surface waters, the subsequent dissolution of sinking biogenic material as well as water mass mixing. This data set supplies information on the spatial distribution of isotopes of Si within water masses from Tahiti to Alaska along GEOTRACES section GP15. This dataset results from leg 1 of the expedition, RR1814; data from RR1815 are available in a separate BCO-DMO dataset.

[GP15 Nd isotopes Leg 1] - Neodymium (Nd) isotopes measured from dissolved seawater on Leg 1 (Seattle, WA to Hilo, HI) of the US GEOTRACES Pacific Meridional Transect (PMT) cruise (GP15, RR1814) on R/V Roger Revelle from September to October 2018 (US GEOTRACES Pacific Meridional Transect (GP15))

The goal of the international GEOTRACES program is to understand the distributions of trace chemical elements and their isotopes in the oceans. Neodymium (Nd) isotopes are widely recognized for their utility as tracers of water transport and as indicators of the sources of trace elements to the oceans. Neodymium isotopes have been designated as "key parameters" to be measured on GEOTRACES expeditions. The data here represent Nd isotopes measured from dissolved seawater on the GP15 GEOTRACES expedition in the Pacific Ocean. The North Pacific is a particularly interesting place to measure Nd isotopes because North Pacific and North Atlantic deep waters represent the two end-members of deep ocean composition, and the few data available so far in the North Pacific differ from expectations based on mixing of known water types. These data are dissolved Nd isotopes measured in profiles at stations on the first leg of the cruise, RR1814.

[GP15 Nitrate d15N and d18O Leg 1] - Nitrate d15N and d18O from Niskin bottle samples collected on Leg 1 (Seattle, WA to Hilo, HI) of the US GEOTRACES Pacific Meridional Transect (PMT) cruise (GP15, RR1814) on R/V Roger Revelle from September to October 2018 (US GEOTRACES Pacific Meridional Transect (GP15))

These data include nitrate δ15N and δ18O along US GEOTRACES GP15, a meridional transect at ~152°W in the Pacific Ocean. The Pacific hosts significant rates of all the fluxes that are relevant to the global N cycle: the N budget fluxes (those that either generate or consume fixed N; N2 fixation and denitrification) as well as the N fluxes from the internal N cycle (those that generate or consume nitrate but leave the fixed N pool unaltered; nitrate regeneration and assimilation). The nitrate δ15N and δ18O provide a useful tool to separate and possibly quantify the overlapping impacts of all these co-occurring processes.

GP15 was a 60-day research cruise that took place in 2018 along a transect form Alaska to Tahiti at 152° W on board of the R/V Revelle. The cruise was completed in two legs (RR1814 and RR1815), which started on the 18th of September and on the 24th of October 2018, respectively. This dataset includes data from Leg 1 (RR1814). Leg 2 data (RR1815) are provided in a separate, related dataset.

[GP15 Particle birefringence photon yield and particle beam attenuation coefficient derived from McLane logging CTD] - Particle birefringence photon yield and particle beam attenuation coefficient derived from a logging CTD deployed during McLane Pump casts on the US GEOTRACES Pacific Meridional Transect (PMT) cruise (GP15) on R/V Roger Revelle from Sept-Nov 2018 (US GEOTRACES Pacific Meridional Transect (GP15))

This data set was derived from a logging CTD deployed during McLane Pump casts as part of the GEOTRACES Pacific Meridional Transect (GP15 expedition). There are several related data files provided. The primary data files include: (1) data for the 0-500 meters (m) depth interval, including measures of particle birefringence photon yield (units of parts per million per meter) and particle beam attenuation coefficient (units of per meter); and (2) 0-500 m McLane optics profiles data by broken down by specific cast number and deployment phase. Supplemental files include data for the full depth of the water column (6000 meters) and CTD data used in the reduction of optical birefringence yield and for the calculation of particle beam attenuation coefficient.
