Alongtrack data from ship's Data Acquisition System (DAS). Dataset Description: <p>Data collected along the cruise track from the ship's IMET sensors, thermosalinograph, Knudesn, and GPS. Unprocessed ADCP, gravity, and multibeam underway data are also available from BCO-DMO upon request by emailing <a href="mailto:info@bco-dmo.org?subject=Request%20for%20TN277%20Underway%20(POWOW%20Project)%20">info@bco-dmo.org</a>. These are raw data that cannot be served online in their current format.</p> Methods and Sampling: <p>The DAS system collects data at an operator selected interval; this interval is usually set at 1 sample every 5 seconds. The data are collected from IMET sensors, SBE-21 Thermosalinagraph, EM302 or Knudsen, C-Nav GPS and Winch systems. The data are time, date and position tagged. A new file is started each day at GMT 0:00 and ends at 23:59:55 (depending on the data storage interval). Filename extensions are Julian Day.

Seasonal and decadal changes in temperature drive Prochlorococcus ecotype distribution patterns
http://oceanography.ml.duke.edu/johnson/research/powow/
Seasonal and decadal changes in temperature drive Prochlorococcus ecotype distribution patterns
<p>Project also known as '<em>Prochlorococcus</em> Of Warming Ocean Waters' (POWOW).</p>
<p>The two numerically-dominant ecotypes of the marine cyanobacterium <em>Prochlorococcus</em> partition the surface ocean niche latitudinally, with ecotype eMIT9312 dominant in the 30 degree N to 30 degree S region and eMED4 dominant at higher latitudes. These ecotypes may account for 25-50% of primary production in open ocean ecosystems, but this percentage is dependent on which ecotype dominates. The relative abundance of the two ecotypes follows a log-linear relationship with temperature, with the transition from eMIT9312 to eMED4 occurring at approx. 18 degrees C. From these descriptive data, it has been hypothesized that temperature is the primary driver of relative abundance. Their contribution to net primary production, however, appears to be independent of temperature, suggesting temperature regulates ecotype dominance through photosynthesis-independent mechanisms.</p>
<p>To test these hypotheses, the PIs are undertaking a series of field and lab studies to investigate the effect of temperature change on the distribution of these ecotypes. Two cruises in the North Pacific will trace the transitions from eMIT9312- to eMED4-dominated regions, with one cruise during the winter and the other during summer. They have hypothesized that the ratio of ecotype abundance will move latitudinally with the seasonal shift in temperature gradient: migration of the 18 degrees C isotherm northward in the summer will be matched by a similar migration of the 1:1 ecotype transition point. Multiple crossings of the 18 degrees C isotherm are proposed, and the summer cruise will also follow the isotherm to the Western US coast to gain insight on physical and geochemical influences. Environmental variables such as nutrient concentrations, light/mixing depths, and virus /grazing based mortality, which may impinge on the relationship between temperature and ecotype ratio, will be assessed through a series of multivariate analyses of the collected suite of physical, chemical and biological data. Seasonal comparisons will be complemented with on-deck incubations and lab competition assays (using existing and new isolates) that will establish, for the first time, how fitness coefficients of these ecotypes relate to temperature. As latitudinal shifts in temperature gradient and migration of ecotypes during seasonal warming likely share common features with high latitude warming as a consequence of climate change, the investigator's analyses will contribute important biological parameters (e.g., abundances, production rates, temperature change coefficients) for modeling biological and biogeochemical responses to climate change. This research will be integrated with that of committed collaborators, generating data sufficient for ecosystem-scale characterizations of the contributions of temperature (relative to other forcing factors) in constraining the range and seasonal migration of these numerically dominant marine phototrophs.</p>

BCO-DMO made the following modifications:
- Parameter names were changed to conform to BCO-DMO conventions.
- Blanks were replaced with 'nd'.
- + signs preceding latitude values were removed.
- lat and lon values that were obviously erroneous were replaced with 'nd' (e.g. negative latitude values, longitude values of -500).
- humidity and sea surface temperature columns were removed because all values were nd (humidity) and -9.999, or -2 (sea surface temp).
- Values containing unreadable characters were replaced with 'nd'.
* Data Version 2 (2021-06-09) replaces version 1 (2012-10-24). There was an unsupported characters in the dataset source files which are assumed to be a corrupt value after trying to read them in over 900 different encoding types. The "bad" characters were changed to "nd" the default missing data identifier.
Below are the line changes between versions 1 and 2. The lines starting with plus sign are the new lines in version 2, the lines starting with a minus are the version 1 lines.

Fluorometer
Fluorometer
PI Supplied Instrument Name: Fluorometer PI Supplied Instrument Description:See the WetLabs ECO Fluorometer chacterization sheet (PDF) from TN277 (POWOW1) cruise. Instrument Name: Fluorometer Instrument Short Name:Fluorometer Instrument Description: A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.

Temperature calibration data
Temperature calibration report
Conductivity calibration data
Conductivity calibration report Instrument Name: Thermosalinograph Instrument Short Name:TSG Instrument Description: A thermosalinograph (TSG) is used to obtain a continuous record of sea surface temperature and salinity. On many research vessels the TSG is integrated into the ship's underway seawater sampling system and reported with the underway or alongtrack data.

Wet Labs CSTAR Transmissometer
PI Supplied Instrument Name: Wet Labs CSTAR Transmissometer PI Supplied Instrument Description:See the WetLabs C-Star calibration sheet (PDF) from the TN277 (POWOW1) cruise. Instrument Name: WET Labs {Sea-Bird WETLabs} C-Star transmissometer Instrument Short Name:WL CSTAR Trans Instrument Description: The C-Star transmissometer has a novel monolithic housing with a highly intgrated opto-electronic design to provide a low cost, compact solution for underwater measurements of beam transmittance. The C-Star is capable of free space measurements or flow-through sampling when used with a pump and optical flow tubes. The sensor can be used in profiling, moored, or underway applications. Available with a 6000 m depth rating.
