        <gco:CharacterString>CICLOPS TMR Hydrography data Dataset Description:  Methods and Sampling: &amp;lt;p&amp;gt;Sensors were deployed on a titanium trace metal rosette (TMR) in tandem with trace metal clean bottle samples during the RVIB Nathaniel B. Palmer cruise (NBP18-01) from December 2017 to February 2018 in coastal Antarctica.&amp;amp;nbsp; TMR casts were performed at 26 stations&amp;amp;nbsp;in the Amundsen Sea, Ross Sea and Terra Nova Bay.&amp;amp;nbsp;Parameters collected include pressure, temperature, conductivity, oxygen, fluorescence, beam transmission, PAR, and salinity.&amp;amp;nbsp;&amp;lt;/p&amp;gt;

&amp;lt;p&amp;gt;The profiles in the dataset are from the up-cast of the TMR cast. More information on sensor data acquisition and processing can be found in &amp;quot;Data Report NBP18-01&amp;quot; from the United States Antarctic Program prepared by Matt Pullen and Bryan Chambers (see&amp;amp;nbsp;Supplemental Docs section).&amp;amp;nbsp;&amp;amp;nbsp;Trace metal rosette sensors are detailed on p.29.&amp;amp;nbsp;&amp;amp;nbsp;&amp;lt;/p&amp;gt;

&amp;lt;p&amp;gt;For all duplicate sensors, the primary sensor was used for temperature and conductivity, and the secondary sensor was used for oxygen in the final hydrography dataset.&amp;lt;/p&amp;gt;

&amp;lt;p&amp;gt;&amp;lt;u&amp;gt;Problem report:&amp;lt;/u&amp;gt;&amp;lt;br /&amp;gt;
The PAR sensor was only included on the TMR beginning at station 35.&amp;lt;/p&amp;gt;</gco:CharacterString>

                            <gco:CharacterString>&lt;p&gt;NSF abstract:&lt;br /&gt;
Phytoplankton blooms in the coastal waters of the Ross Sea, Antarctica are typically dominated by either diatoms or Phaeocystis Antarctica (a flagellated algae that often can form large colonies in a gelatinous matrix). The project seeks to determine if an association of bacterial populations with Phaeocystis antarctica colonies can directly supply Phaeocystis with Vitamin B12, which can be an important co-limiting micronutrient in the Ross Sea. The supply of an essential vitamin coupled with the ability to grow at lower iron concentrations may put Phaeocystis at a competitive advantage over diatoms. Because Phaeocystis cells can fix more carbon than diatoms and Phaeocystis are not grazed as efficiently as diatoms, the project will help in refining understanding of carbon dynamics in the region as well as the basis of the food web webs. Such understanding also has the potential to help refine predictive ecological models for the region. The project will conduct public outreach activities and will contribute to undergraduate and graduate research. Engagement of underrepresented students will occur during summer student internships. A collaboration with Italian Antarctic researchers, who have been studying the Terra Nova Bay ecosystem since the 1980s, aims to enhance the project and promote international scientific collaborations.&lt;/p&gt;
&lt;p&gt;The study will test whether a mutualistic symbioses between attached bacteria and Phaeocystis provides colonial cells a mechanism for alleviating chronic Vitamin B12 co-limitation effects thereby conferring them with a competitive advantage over diatom communities. The use of drifters in a time series study will provide the opportunity to track in both space and time a developing algal bloom in Terra Nova Bay and to determine community structure and the physiological nutrient status of microbial populations. A combination of flow cytometry, proteomics, metatranscriptomics, radioisotopic and stable isotopic labeling experiments will determine carbon and nutrient uptake rates and the role of bacteria in mitigating potential vitamin B12 and iron limitation. Membrane inlet and proton transfer reaction mass spectrometry will also be used to estimate net community production and release of volatile organic carbon compounds that are climatically active. Understanding how environmental parameters can influence microbial community dynamics in Antarctic coastal waters will advance an understanding of how changes in ocean stratification and chemistry could impact the biogeochemistry and food web dynamics of Southern Ocean ecosystems.&lt;/p&gt;</gco:CharacterString>

                <gco:CharacterString>&amp;lt;p&amp;gt;Sensors were deployed on a titanium trace metal rosette (TMR) in tandem with trace metal clean bottle samples during the RVIB Nathaniel B. Palmer cruise (NBP18-01) from December 2017 to February 2018 in coastal Antarctica.&amp;amp;nbsp; TMR casts were performed at 26 stations&amp;amp;nbsp;in the Amundsen Sea, Ross Sea and Terra Nova Bay.&amp;amp;nbsp;Parameters collected include pressure, temperature, conductivity, oxygen, fluorescence, beam transmission, PAR, and salinity.&amp;amp;nbsp;&amp;lt;/p&amp;gt;

&amp;lt;p&amp;gt;The profiles in the dataset are from the up-cast of the TMR cast. More information on sensor data acquisition and processing can be found in &amp;quot;Data Report NBP18-01&amp;quot; from the United States Antarctic Program prepared by Matt Pullen and Bryan Chambers (see&amp;amp;nbsp;Supplemental Docs section).&amp;amp;nbsp;&amp;amp;nbsp;Trace metal rosette sensors are detailed on p.29.&amp;amp;nbsp;&amp;amp;nbsp;&amp;lt;/p&amp;gt;

&amp;lt;p&amp;gt;For all duplicate sensors, the primary sensor was used for temperature and conductivity, and the secondary sensor was used for oxygen in the final hydrography dataset.&amp;lt;/p&amp;gt;

&amp;lt;p&amp;gt;&amp;lt;u&amp;gt;Problem report:&amp;lt;/u&amp;gt;&amp;lt;br /&amp;gt;
The PAR sensor was only included on the TMR beginning at station 35.&amp;lt;/p&amp;gt;</gco:CharacterString>

The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics Community Standard Description: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/</gco:CharacterString>

  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.

The ECO series excels in biological monitoring and dye trace studies. The potted optics block results in long term stability of the instrument and the optional anti-biofouling technology delivers truly long term field measurements.
