This dataset contains chemical data collected on R/V Falkor during cruise FK141215 in the North Pacific Ocean on 2014-12-16. These data include Ammonium, Nitrate, Nitrite, SiOH_4, and reactive phosphorus (PO4). The instruments used to collect these data include Leggo Lander, Niskin bottle, and Nutrient Autoanalyzer. These data were collected by Douglas Bartlett of University of California-San Diego as part of the "Patterns of Microbial Community Structure Within and Between Hadal Environments (Mariana Perspectives)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-01-21.

The following is the text of the dataset description provided by BCO-DMO:

General nutrient data (averages) from Leggo drop 1 seawater

Dataset Description:
General nutrient data (averages) from Leggo drop 1 seawater collected by 3L Niskin bottle.

NOTE: sample RG10 in this dataset is equivalent to RG09 in the event log, due to at-sea recording error. RG10-2 is equivalent to RG10 in the event log.

Supplemental Information
Acquisition Description:
This data set is associated with PI Douglas Bartlett (NSF OCE-1536776) and Schmidt Ocean Institute R/V Falkor cruise FK141215. The cruise occurred December 15-21, 2014 in the Challenger Deep within the territorial waters of the Federated States of Micronesia. During this cruise the Leggo lander was deployed multiple times and drops 1 and 3 recovered seawater samples that were analyzed. Additional details can be found at: https://schmidtocean.org/cruise/expanding-mariana-trench-perspectives/ and https://scripps.ucsd.edu/labs/dbartlett/contact/challenger-deep-cruise-2014/

Leggo Lander Drop 1:
Time (in Guam) deployed/recovered: December 16, 9:00/19:26.
Position at deployment: 11° 21.9836 N 142° 25.9533 E, middle section of the Challenger Deep.
Greatest depth of dive: approximately ~10,900 m.
In situ temperature on seafloor: 2.6°C.
Notes: This drop recovered seawater samples from about a meter off the seafloor. This included a 3 L Niskin bottle of seawater and ~ 150 mls of seawater collected in a pressure-retaining seawater sampler. The PRS sampler held more than 81% of the in situ pressure.

Nutrients:
Seawater nutrients were measured from the 3 liter Niskin bottle used during the first drop of Leggo Lander. The description of general inorganic nutrient measurements performed by Scripps Institution of Oceanography Shipboard Technical Support can be found at https://scripps.ucsd.edu/ships/shipboard-technical-support/odf/chemistry-services/nutrients
Purpose This dataset is available to the public for a wide variety of uses including scientific research and analysis.
