<div><p><strong>Surface sampling:</strong></p>
<p>For the YSI, this was done off the side of the boat, at 1m depth. For the Aqufluor, this was done by swimming out from the boat, ~10m away from the vessel to avoid contamination from paint chips, gasoline, etc.</p>
<p><strong>Other Sampling:</strong></p>
<p>Bottom depth at all sampling locations was 10m.</p>
<p>YSI Measurements: Place YSI sensor into the water, and lower to 1m depth. Wait for readings to stabilize, and then record all parameters.</p>
<p>AquaFluor measurement procedure:</p>
<p>1. Test solid secondary standard and turbidity standard to ensure the instrument has not drifted throughout the day. Use this same procedure. Compare to the measurement from the beginning of the calibration.<br />
2. Turbidity and In vivo Chl a will either be collected independently and taken as a subsample of the for chl a samples<br />
3. In either case a 500 mL Nalgene bottle will be used, and should be collected in the same matter as the chl a sample (see 1.1)<br />
4. Take as many independent chlorophyll and turbidity samples as you can but you will only take one sub-set sample from the extracted chlorophyll nalgenes.<br />
5. When conducting the independent sampling, you will reuse one 500 ml brown nalgene. Wash with sterile seawater in-between samples.<br />
6. Fill the cuvette 3/4 of the way using a transfer pipette. If you get the outside of the cuvette wet, dry completely with a kimwipe.<br />
7. For the sub-samples of extracted chlorophyll, use the same 30cc syringe as used for nutrients.<br />
8. Insure cleanliness of the cuvette, which are dry on the outside<br />
9. Insert the sample (be aware of orientation), the black sample compartment does not need to be closed when reading the sample<br />
10. Press the <Read> button. The instrument will measure and average the fluorescence signal for 10 seconds<br />
11. The reading result will display on the top line of the Home screen, log this result<br />
12. The top left corner will then display “WAIT” for 3 seconds. Once “WAIT” disappears, another sample can be read<br />
13. We are going to reuse cuvettes. After you complete one sample clean the cuvette with sterile seawater and dry completely with a kimwipe. Additionally, clean the transfer syringe used for the sample with sterile seawater and dry with a kimwipe.</p></div>
Surface water quality samples
<div><p>This dataset contains water quality measurements collected on Kiritimati island, Kiribati in 2014 and 2015. Measured parameters include water temperature, salinity, pH, chlorophyll, turbidity, and dissolved oxygen. Values of yes or no are also supplied to describe whether it was raining or windy at the time the samples were taken.</p></div>
Kiritimati 2014-2015: Surface water
<div><p>Data are directly from field readings.</p>
<p><strong>BCO-DMO Processing Notes:</strong></p>
<p>* added a conventional header with dataset name, PI name, version date<br />
* modified parameter names to conform with BCO-DMO naming conventions<br />
* values of NA changed to nd for no data<br />
* removed Kiritimati,Kiribati for location/country in the data since it was same throughout. Described in the metadata.<br />
* removed second depth value (bottom depth) which was 10m for all samples. Included this information in the acquisition description.</p></div>
