attribute NC_GLOBAL acquisition_description String Multiple deployments of two Sea-Bird Scientific Navis BGCi floats (numbers\nF033 and F034) equipped with CTDs, transmissometers, O2 optodes,\nbackscattering (700 nm), fluorescence (chlorophyll, colored dissolved organic\nmatter), and tilt sensors were conducted between July 2013 and November 2014\nin conjunction with Bermuda Atlantic Time-series Study cruises. Short-term\ndeployments (1.5 \\u2013 3 days) followed by recovery of the floats were\nconducted during four monthly BATS cruises in July \\u2013 October 2013 and one\ncruise in March 2014. Both floats were deployed during the July and August\n2013 cruises and float F034 was deployed for the remaining cruises. Each float\ncollected one profile per cruise with the exception of the August 2013 cruise,\nduring which the two floats together collected 13 profiles. During short-term\ndeployments, floats first completed an initial descent and ascent without\nparking, then completed 1 or 2 more profile cycles with different, consecutive\ntarget depths. Following the initial descent/ascent described above, the\nshort-term profile cycles were structured as described below for long-term\ndeployments. In addition to the short-term cruise deployments, F033 profiled\ncontinuously from October 2013 until early April 2014, yielding 77 profiles,\nand F034 profiled continuously from March 2014 until late November 2014,\nyielding 139 profiles. During these long-term deployments, a typical cycle\nconsisted of 1) the descent to the target park depth, 2) a park phase at the\ntarget depth lasting 1.5 \\u2013 2.5 days during which measurements are made\nevery 15 minutes, 3) a descent to 1000 dbar, 4) an ascent to the surface\nduring which measurements are made, and 5) a surface telemetry phase, during\nwhich a GPS fix is obtained, data are uploaded via Iridium, and instructions\nfor the next cycle are downloaded. During long-term deployments, floats cycled\nthrough park phases at 150/200, 300, 500, and 1000 dbar every 7 days, spending\n2.5 days at 1000 dbar and 1.5 days at the shallower depths. The sequence of\npark phase depth at the three shallowest depths was varied between each 7-day\ncycle over a 21-day period to avoid aliasing in particle flux profiles.\n \nRefer to [https://www.bco-dmo.org/project/2124](\\\\\"http://www.bco-\ndmo.org/project/2124\\\\\") or\n[http://bats.bios.edu](\\\\\"http://bats.bios.edu/\\\\\") for a description of BATS\nbottle sample acquisition.

attribute NC_GLOBAL project String RapAutParticleFlux
attribute NC_GLOBAL projects_0_acronym String RapAutParticleFlux
attribute NC_GLOBAL projects_0_description String Particles settling into the deep ocean remove carbon and biologically-important trace elements from sunlit, productive surface waters and from contact with the atmosphere over short timescales. A shifting balance among physical, chemical, and biological processes determines the ultimate fate of most particles at depths between 100 and 1,000 m, where fluxes are hardest to measure. Our challenge is to expand the number of particle flux observations in the critical \"twilight zone\", something that has proven elusive with ship-based “snapshots” that have lengths of, at most, a few weeks. Here, we propose an optical, transmissometer-based method to make particle flux observations from autonomous, biogeochemical profiling floats. Novel developments in data interpretation, sensor operation, and platform control now allow flux measurements at hourly resolution and give us observational access to the water-column processes driving particle flux over short timescales. The sensors and float platforms that we propose to use are simple, robust, and commercially-available, making them immediately compatible with community-scale efforts to implement other float-based biogeochemical measurements.\nWe have two main goals:  First, we will quantify particulate organic carbon (POC) flux using float-based optical measurements by validating our observations against fluxes measured directly with neutrally-buoyant, drifting sediment traps. Second, we will evaluate the contribution of rapid export events to total POC fluxes in the oligotrophic ocean by using a biogeochemical profiling float to collect nearly-continuous, depth-resolved flux measurements and coupled, water-column bio-optical profiles. \nTo achieve these goals, we will implement a work plan consisting of 1) a set of laboratory-based sensor calibration experiments to determine detection limits and evaluate sensitivity to particle size; 2) a series of four sediment trap and biogeochemical float co-deployments during which we will collect POC flux and field calibration data; and 3) a long-term sampling and analysis period (approximately 1 year) during which data will be returned by satellite from the biogeochemical float. We will conduct calibration fieldwork in conjunction with monthly Bermuda Atlantic Time-series Study (BATS) cruises, taking advantage of the timeseries measurements and the context provided by the 25-year record of POC flux at that site. The data returned by the float will comprise the first quantitative particle flux observations made at high-enough temporal resolution to interpret in the context of short-term, upper-ocean production events.

attribute NC_GLOBAL summary String Optical proxy measurements of sinking particle flux and water-column bio-optical profiles were obtained from profiling floats in the Sargasso Sea to expand the number of particle flux observations in the critical and under-sampled \\u201ctwilight zone\\u201d. Factory and field calibration data for dissolved oxygen, beam transmission, optical backscatter, chlorophyll fluorescence and colored dissolved organic matter sensors are provided. Float oxygen, chlorophyll fluorescence, and backscatter sensors were additionally cross-calibrated to bottle samples for oxygen, HPLC chlorophyll, and particulate organic carbon collected during concurrent Bermuda Atlantic Time-series Study (BATS) cruises prior to months-long deployment of the floats in the Sargasso Sea.
