Carbon:234Thorium ratios of sinking particles collected by sediment trap and large particles collected by in situ pump on CCE-LTER Process Cruises. 2006 - 2017 (ongoing).
The ratio of carbon to 234Thorium on particles can be used to convert water column 234Th measurements to sinking carbon flux estimates and to investigate particle scavenging in the ocean. Carbon:234Th ratios of two types of particles are measured: true sinking particles collected by sediment trap and large (>50-µm) particles collected using a McLane in situ Pump. Sinking particles are collected in VERTEX-style particle interceptor traps (PIT) with an 8:1 aspect ratio, 70-mm diameter, and a baffle on top comprised of 13 smaller beveled tubes with a similar 8:1 aspect ratio. Tubes are deployed with a formalin-brine for a duration of 2-5 days. After recovery, samples were gravity filtered through a 200-µm filter. The 200-µm filtered was then immediately examined under a stereomicroscope and mesozooplankton swimmers were removed from the sample. On P0704, P0810, and P1106 cruises the remaining (non-swimmer) portion of the material on the >200-µm filter was then re-combined with the <200-µm portion of the sample. Samples were then filtered through a pre-combusted quartz (QMA) filter. On P1208, P1604, and P1706 cruises the >200-µm and <200-µm fractions were filtered separately onto QMA filters to determine C:234Th ratios of different size classes of sinking particles. Typically, triplicate whole PIT tubes were filtered for C:234Th ratios. However, on some cycles with very high flux, samples were first split on a Folsom splitter. On some cycles, the mesozooplankton ‘swimmers’ were saved and filtered onto a separate QMA filter to quantify the C:234Th ratio of mesozooplankton. QMA filters were all dried and mounted in RISO sample holders. >50-µm particles were also collected using McLane in situ pumps (typically deployed for a period of ~1 hour at the same depth of the sediment traps). In situ pump samples were rinsed off of the 147-mm nitex mesh filters used with the pump onto a pre-combusted QMA filter, which was similarly dried and mounted in a RISO sample holder. Samples
Three ~50m vertical profiles of the dissolved O2/Ar ion current ratio in seawater with depth, measured at high vertical resolution using Membrane Inlet Mass Spectrometry. 2017.
Seawater was sampled via tubing with depth between the surface and ~50m, then measured for the ion current ratio of dissolved O2/Ar using Membrane Inlet Mass Spectrometry (Tortell, 2005; Kaiser et al., 2005). Measurements were conducted during the P1706 CCE-CalCOFI Process Cruise (1 Jun - 2 Jul 2017). Profiles were taken on 11 June, 15 June, and 25 June during Cycle 1, Cycle 2, and Cycle 4, respectively. Oxygen saturation and solubility were separately and concurrently measured from sampled seawater using an Aanderaa optode oxygen sensor. The ratio of seawater O2/Ar to the O2/Ar ratio at equlibration with the atmosphere is also reported. Vertical profiles of O2/Ar are used to correct surface measurements of productivity using O2/Ar for vertical influences, and can also be used to qualitatively assess profiles of community metabolic activity with depth.

Bowen Ratio Surface Flux: GSFC (FIFE)
The Bowen Ratio Surface Flux Observations (GSFC) Data Set contains data collected using the Bowen Ratio Techniques. The major data collection effort was conducted in 1987 when 16 stationary sites were equipped with Bowen ratio equipment by different groups. Surface flux measurements were made at selected sites within the FIFE area. All measurements are from a single upland site that was grazed. This station measured the fluxes of net radiation, sensible heat, and latent heat and several micrometeorological parameters.

BlueFlux Airborne Trace Gases, Fluxes, and Mixing Ratios, Southern Florida, 2022-2023
This dataset includes airborne in situ measurements of greenhouse gas mixing ratios, meteorological parameters, and fluxes (CO2, CH4, latent heat fluxes, friction velocity, and convective velocity scale) calculated with wavelet transforms. CO2, CH4, CO, O3, and water vapor mixing ratios, and meteorological variables were obtained from a Beechcraft A90 King Air aircraft. Flights occurred on April 19-26 2022, October 14-20 2022, February 5-13 2023, and April 13-19 2023 as part of the BlueFlux campaign, funded by NASA's Carbon Monitoring System program. Measurements were made with several instruments, including a PICARRO 2401-m (0.5 Hz CO2/CH4/H2O/CO), PICARRO 2311-f (10 Hz CO2/CH4/H2O), NASA Rapid Ozone Experiment (ROZE, 10 Hz O3), and AIMMS-20 probe (3-D winds, meteorology, and aircraft location data). Flight lines span Everglades National Park (ENP) and Big Cypress National Preserve (BCNP) in southern Florida, USA. The measurements were used to calculate vertical fluxes of trace gases and heat via wavelet transform eddy covariance
