Brief Description | DO and temperature from soloDO logger measured with Alvin |
In situ sensor data was collected by Alvin with the soloDO logger (RBR Ltd., Canada). The prototype recorded temperature using an internal RBR probe (0.0018 C resolution), and dissolved oxygen using an Aandera DO probe.
The R/V Atlantis cruise AT26-24 went to Dorado Outcrop off the west coast of Costa Rica in the Pacific Ocean at location 9 degrees 5.5 minutes north, 87 degrees 6.0 minutes west. For more information about operations of this cruise see the AT26-24 deployment page and cruise report.
The data have not been processed further.

Date/Time (UTC) ISO formatted
This standard is based on ISO 8601:2004(E) and takes on any of the following forms:
2009-08-30T09:05:00[.xx] (local time)
2009-08-30T14:05:00[.xx]Z (UTC time)
2009-08-30T14:05:00[.xx]-05:00
The dashes and the colons can be dropped.
The T can also be dropped "by mutual agreement", but one needs the trailing Z if the time is UTC.
Sample ISO_datetime_utc:

Temperature
Oxygen; dissolved; reported in units of micromoles/liter
Approximate latitude of sampling area (Dorado Outcrop)
latitude, in decimal degrees, North is positive, negative denotes South; Reported in some datasets as degrees, minutes
Approximate longitude of sampling area (Dorado Outcrop); west is negative
longitude, in decimal degrees, East is positive, negative denotes West; Reported in some datsets as degrees, minutes
Date (UTC) in format yyyy-mm-dd
date; generally reported in GMT as YYYYMMDD (year; month; day); also as MMDD (month; day); EqPac dates are local Hawaii time. ISO_Date format is YYYY-MM-DD (http://www.iso.org/iso/home/standards/iso8601.htm)

Description from NSF award abstract:
Pristine fluids from a typical ridge-flank hydrothermal system have never been sampled, mainly because it has not been possible to locate a site of focused discharge where representative samples could be collected. The PIs have located a small basement feature, Dorado outcrop, on 23 m.y.-old seafloor on the eastern flank of the East Pacific Rise that they plan to sample to determine the fluid composition, and to assess the rate of discharge from the outcrop, so that they can quantify the chemical impact of this hydrothermal system. They plan an 18-day expedition that combines the surveying capabilities of the AUV Sentry (bathymetric, sub-bottom sonar, photo mosaics, water column anomalies) and an ocean-class vessel capable of collecting high-quality multi-beam data and CTD samples, and supporting the survey and sampling capabilities of the ROV Jason II for collection of spring and plume fluids, heat flow data, sediment push cores, and still and video photography. These data and samples will be combined hopefully to generate the first well-constrained estimates of hydrothermal flows from Dorado outcrop. This expedition will result in the collection of samples and data from a “fire hose” of ridge-flank, hydrothermal system, challenging the commonly held view that discharge from ridge flank hydrothermal systems occurs primarily from diffuse seeps.
