TDN =&amp;amp;nbsp;&amp;amp;nbsp;total dissolved nitrogen&amp;lt;br /&amp;gt;
GF/F =&amp;amp;nbsp;glass fiber filter&amp;amp;nbsp;&amp;lt;/p&amp;gt; Methods and Sampling: &amp;lt;p&amp;gt;TEP and CSP particles were collected onto 0.4 µm polycarbonate filters from 1 liter each of whole water collected via the CTD/Rosette Niskin bottles into 1 L polycarbonate media bottles. Filtration was achieved using a peristaltic pump and silicone tubing through a 25 mm polycarbonate filter holder. Filters containing particles were immediately stained with Alcian blue (TEP) or Coomassie blue (CSP) dyes and stored frozen at -20degC until analysis on shore back at the University of New Hampshire. TEP and CSP particle concentrations were measured following the spectrophotometric method of Bittar et al. 2018 in Limnology &amp;amp;amp; Oceanography Methods (doi:10.1002/lom3.10268) and standardized with xanthan gum and bovine albumen respectively. Total dissolved carbohydrates were measured using the spectrophotometric method of Myklestad et al. 1997 in Marine Chemistry (doi:10.1016/S0304-4203(96)00074-6). Seawater samples were previously filtered via gravity filtration and silicone tubing connected to Niskin bottles at sea, passed through a 47mm glass fiber filter (GF/F; 0.7 µm) held in a polycarbonate filter holder, into 40 mL glass EPA vials with silicone septa tops and frozen at -20degC until analysis on shore back at the University of New Hampshire. Temperature, salinity, fluorescence, and dissolved oxygen were measured by the ship's CTD sensor package on the downcast. Dissolved nitrate + nitrite, phosphate, silicate, and ammonium were measured by the University of Hawaii-Manoa's S-LAB using a Seal Analytical AA3 HR Nutrient Autoanalyzer using standard colorimetric protocols (https://www.soest.hawaii.edu/S-LAB/equipment/slab_autoanalyzer.htm). Dissolved organic phosphorus and dissolved organic nitrogen were computed after subtracting the relevant inorganic nutrient concentrations from the measured total dissolved phosphorus (TDP) and total dissolved nitrogen concentrations (TDN). TDP was measured using the ash-hydrolysis method of Solorzano and Sharp 1980 (doi:10.4319/lo.1980.25.4.0754) and TDN was measured by persulfate oxidation using the protocols within Knapp et al. 2005 (doi:10.1029/2004GB002320)&amp;lt;strong&amp;gt; &amp;lt;/strong&amp;gt;with chemiluminescent detection of the resulting nitrate after reduction to NOx gas using the Braman and Hendrix 1989 method (Braman, R. S., &amp;amp;amp; Hendrix, S. A. (1989, doi: 10.1021/ac00199a007); both at the University of New Hampshire.&amp;lt;/p&amp;gt;</gco:CharacterString>

The ocean is usually layered, with light and oxygen in the warmer surface and nutrients at the cooler depths. Biological and physical processes determine this distribution. Marine algae grow in the well-lit upper layers but need nutrients to grow. However, in the subtropics, the ocean's largest biome, the relationship between oxygen and nitrate (a key nutrient required for photosynthesis) is different from expected. Two processes could explain this. Nutrients could be transported upward by migrating giant single-celled algae (phytoplankton). Another explanation is that the production of an organic material called transparent exopolymer (TEP) takes up carbon without using nutrients or exporting carbon to depth, as would occur in photosynthesis. While both processes could be occurring, the relative contribution of migrating phytoplankton versus TEP would tell us whether the observed oxygen pattern in the upper ocean results from photosynthesis. This problem relates to the general question of where and how nutrients reach the well-lit surface waters to enable photosynthesis. These hypotheses are tested at the Hawaii Ocean Time-Series using in-situ camera systems to image and quantify the giant phytoplankton and direct water samples to measure the vertical distribution of TEP. The data are entered into numerical models to calculate the nitrate to oxygen relationships and add information about the carbon cycle. In addition to training of undergraduate students and a postdoctoral fellow, the cruises provide an opportunity to prepare a cadre of communication fellows who will develop materials and media, including videos, to translate this highly complex scientific concepts for the general public. The social media campaign #SaveOur70 provides a valuable venue to reach and engage with the public.&lt;/p&gt;
&lt;p&gt;Quantifying nutrient transport, utilization, and its relationship to carbon drawdown in the subtropical gyres is fundamental to our understanding of the carbon cycle. Geochemical distributions from the well-characterized time-series sites near Hawaii and Bermuda have long-served to identify previously unknown links between subsurface nitrate fields, summertime dissolved inorganic carbon (DIC) drawdown, and net community production in the absence of known nutrient sources. Two recently suggested processes rise to prominence to explain anomalies in subtropical distributions of dissolved carbon, oxygen, and nitrate in the upper ocean: 1) nutrient transport by giant phytoplankton that vertically migrate, and 2) cycling of low N organic matter between the mixed layer and the upper nutricline as transparent exopolymer particles (TEP) or gel-like organic material (GLOM). While linked at a fundamental level (phytoplankton are TEP producers), the outcome of the two processes are distinct. Vertical migration of phytoplankton is an active transport of nitrate, acquired in the nutricline, to the surface. There is an implication of subsequent reduction, photosynthetic carbon fixation and eventual export. TEP/GLOM cycling results in apparent DIC drawdown but there is no net export out of the surface layer and no requirement for additional nutrient sources in the mixed layer. This project collects the data to quantify the contribution of these two processes to the observed anomalies in nitrate to oxygen distribution at the time-series station at Hawaii (HOT). This is accomplished by enumerating the vertically migrating, aflagellate flora (VMF), implementing a 1-D model on vertical migration, and coupling these results with a 1-D model of the contribution of N-poor carbon cycling patterns in the upper water column derived from TEP and carbohydrate measurements. The combined VMF and TEP/GLOM 1-D models are used to model the dissolved oxygen, carbon, and nitrate budgets at HOT allowing for attribution of both hypothesized processes to the observed preformed nitrate distribution, its formation rate, and summertime inorganic carbon drawdown.&lt;/p&gt;</gco:CharacterString>

                <gco:CharacterString>&amp;lt;p&amp;gt;TEP and CSP particles were collected onto 0.4 µm polycarbonate filters from 1 liter each of whole water collected via the CTD/Rosette Niskin bottles into 1 L polycarbonate media bottles. Filtration was achieved using a peristaltic pump and silicone tubing through a 25 mm polycarbonate filter holder. Filters containing particles were immediately stained with Alcian blue (TEP) or Coomassie blue (CSP) dyes and stored frozen at -20degC until analysis on shore back at the University of New Hampshire. TEP and CSP particle concentrations were measured following the spectrophotometric method of Bittar et al. 2018 in Limnology &amp;amp;amp; Oceanography Methods (doi:10.1002/lom3.10268) and standardized with xanthan gum and bovine albumen respectively. Total dissolved carbohydrates were measured using the spectrophotometric method of Myklestad et al. 1997 in Marine Chemistry (doi:10.1016/S0304-4203(96)00074-6). Seawater samples were previously filtered via gravity filtration and silicone tubing connected to Niskin bottles at sea, passed through a 47mm glass fiber filter (GF/F; 0.7 µm) held in a polycarbonate filter holder, into 40 mL glass EPA vials with silicone septa tops and frozen at -20degC until analysis on shore back at the University of New Hampshire. Temperature, salinity, fluorescence, and dissolved oxygen were measured by the ship's CTD sensor package on the downcast. Dissolved nitrate + nitrite, phosphate, silicate, and ammonium were measured by the University of Hawaii-Manoa's S-LAB using a Seal Analytical AA3 HR Nutrient Autoanalyzer using standard colorimetric protocols (https://www.soest.hawaii.edu/S-LAB/equipment/slab_autoanalyzer.htm). Dissolved organic phosphorus and dissolved organic nitrogen were computed after subtracting the relevant inorganic nutrient concentrations from the measured total dissolved phosphorus (TDP) and total dissolved nitrogen concentrations (TDN). TDP was measured using the ash-hydrolysis method of Solorzano and Sharp 1980 (doi:10.4319/lo.1980.25.4.0754) and TDN was measured by persulfate oxidation using the protocols within Knapp et al. 2005 (doi:10.1029/2004GB002320)&amp;lt;strong&amp;gt; &amp;lt;/strong&amp;gt;with chemiluminescent detection of the resulting nitrate after reduction to NOx gas using the Braman and Hendrix 1989 method (Braman, R. S., &amp;amp;amp; Hendrix, S. A. (1989, doi: 10.1021/ac00199a007); both at the University of New Hampshire.&amp;lt;/p&amp;gt;</gco:CharacterString>

            <gco:CharacterString>PI Supplied Instrument Name:  Instrument Name: Sea-Bird SBE-4 Conductivity Sensor Instrument Short Name:SBE-4 Conductivity   Instrument Description: The Sea-Bird SBE-4 conductivity sensor is a modular, self-contained instrument that measures conductivity from 0 to 7 Siemens/meter.  The sensors (Version 2; S/N 2000 and higher) have electrically isolated power circuits and optically coupled outputs to eliminate any possibility of noise and corrosion caused by ground loops. The sensing element is a cylindrical, flow-through, borosilicate glass cell with three internal platinum electrodes. Because the outer electrodes are connected together, electric fields are confined inside the cell, making the measured resistance (and instrument calibration) independent of calibration bath size or proximity to protective cages or other objects.
