Why was the data set created?

The goals of our study are: (1) to quantify physical and chemical properties of terrestrial runoff in "real time" as it enters the coastal water/coral reef ecosystem of southern Kaneohe Bay, (2) to characterize temporally physical and biogeochemical processes, that may affect the coastal/reef ecosystem, (3) to obtain time-series data on the biogeochemical evolution of the water column and reef study site under various environmental conditions, (4) to quantify the importance of storm-derived nutrients in both the dissolved and particulate load to productivity in the bay, and (5) to demonstrate that the remobilization, remineralization, and resuspension of particulate nutrients pulsed to the sea floor during storm plume events are important to nutrient subsidies in bay waters and may be sustaining the productivity of nuisance algae in the bay.

Storm events were defined as greater than 5.1 cm of rain at the Luluku rain gain in less than 24 hours. The nine southern bay stations were sampled daily for one week after or until no obvious visual evidence of the storm runoff remained. Surface seawater samples were collected in 10% HCI-washed, one-liter bottles to be analyzed for chlorophyll-a and dissolved inorganic nutrients. These include nitrate (NO3-) plus nitrite (NO2-), phosphate (PO43-), ammonium (NH4+), and dissolved silica (SiCo2). Water samples for nutrients and chlorophyll-a were kept in a cooler while in the field, were stored in a laboratory refrigerator until filtration (usually done immediately upon returning to the lab, or later the same day), and were frozen after filtration until analysis. Surface water samples were also collected in 300 mL, borosilicate glass(BOD-type) bottles for Total Alkalinity (TA) analysis. The bottles were rinsed three times with surface water, held just below the surface to collect the sample, and then a small amount of water was removed from the bottle (to about 2-3 cm below the stopper) to allow for equilibration of air and seawater. The samples were immediately poisoned with 200 uL of a stauratedmercuric chloride (HgCl2) solution to kill any organisms present in the sample. The bottles were then sealed using Apiezon (non silicone-based)grease on the stopper and fastened using a rubber band and bottle clip. The TA samples were collected once or twice per month at the CRIMP-CO2 buoy location. On selected sampling dates, duplicate BOD bottles were collected for dissolved inorganic carbon (DIC) analysis. Profiles of water column properties were also taken at each station using a YSI 6600 sonde. Parameters were measured at two-second intervals. The sonde was calibrated no more than two days prior to each sampling date and was checked post-sampling to verify the calibration. The chlorophyll calibration was conducted in the dark and the sonde was always lowered off the shady side of the boat in order to reduce light interference with the fluorescence measurement. At each station, the sonde was lowered through the water at a rate no greater than 0.06-0.12 m/s (4-8 samples/m), and even slower near the surface to maximize resolution of the surface layer. Analyses Total Alkalinity (TA)TA samples were filtered through 0.45 um pore size Millipore type HA(nitrocellulose) filters to remove particulate organic and inorganic matter that could interfere with the analysis. TA samples were analyzed using an open cell, potentiometric Gran titration method in conjunction with a computerized (Brinkmann Metrohm) titrator, Orion pH meter, and Accumetcolomel-reference combination pH electrode. The pH electrode was calibrated using pH 4 and pH 7 (NBS) buffers. The room temperature generally varied between 20 - 23 degree C and was monitored throughout titrations. The pH electrode was recalibrated if the room temperature change exceeded 1-2 deg C. Electrodes were only used if the response was greater than 97% Nernstian. The0.1 N (analytical grade) hydrochloric acid (HCI) standard used for the titrations contained 0.7 moles of NaCl to adjust to the ionic strength of seawater. The HCI titrant was standardized periodically with certified reference material (CRM) to determine the exact concentration of the acid. Approximately 40 mL of sample were weighed on an analytical balance and the weights were entered into the computer program. The samples were run induplicate (60%) or triplicate (40%), and a CRM sample was run at the start and end of each day as well as between every five samples (to monitor accuracy).If replicate analyses were not sufficiently precise (i.e., < 8 ueq/kg apart),an additional replicate was run. The average precision between replicate samples for all TA titrations was 0.16%, and the average accuracy was +/- 4.22ueq/kg. The average standard deviation of TA sample replicates from theCRIMP-CO2 buoy station was 2.55 ueq/kg. Nutrients Nutrient samples were stored in a refrigerator (to delay biological uptake),generally for less than one day, before they were filtered with 1.2 um nominalpor size Whatman GF/C filters, which were pre-rinsed with HCI and DI water. Filtered samples were then frozen until analysis. Nutrient samples were either sent out for analysis to an EPA certified lab, or were run using a Technicon visible light spectrophotometer and auto-analyzer. Samples collected after June 15, 2006, were not analyzed for nutrients. Chlorophyll Approximately 70 mL of a samples were filtered through a Whatman GF/C filter for chlorophyll analysis. Filters were stored in small glass centrifuge tubes in the freezer until analysis. Chlorophyll was determined using the fluorometric method for acetone-extracted samples. The fluorometer was calibrated using a two-point calibration using acetone and a commercial chlorophyll source from Sigma Chemical (which contains no phaeophytin). This analysis was performed before and after the sample was acidified with 0.1 NHCl in order to determine the amount of chlorophyll-a present in the sample as well as the concentration of degraded (phaeophytin) pigments. The detection limit and precision of this method are 0.01 ug/L and 5%, respectively.
