Continuous water quality monitoring to determine the cause of coral reef ecosystem degradation for coastal windward Oahu streams during 2002 (NCEI Accession 0001070)

Kaneohe and Waimanalo streams on the windward side of the island of Oahu in the Hawaiian Islands have been hardened to prevent flooding. The hardening process has involved elimination of the natural riparian habitat and replacement of the natural stream channel with a concrete-lined conduit having vertical walls and a broad, flat bottom. The shallow depth of the water column and the absence of shade have resulted in temperatures that average as much as 4-5ÂºC above ambient and rise as high as 32ÂºC during daylight hours. Unlike most low-order streams, the hardened sections of both streams are autotrophic, as evidenced by elevated pH values and O2 concentrations as high as 150% of saturation. Several allochthonous inputs, one from a storm sewer and the other from a natural spring, introduced water with anomalously low O2 concentrations and very high nitrate concentrations. The absence of sediments in the hardened sections of the streams precludes natural sedimentary microbial processes, including denitrification. Nitrate concentrations in a section of Waimanalo Stream with a natural streambed drop dramatically from values in excess of 400 ÂµM to concentrations less than 10 ÂµM at the head of the estuary. Although some of this decline is due to dilution with seawater, the concentration of nitrate at the head of the estuary is only 10% of the value that could be explained by dilution effects. Biological processes associated with a natural streambed thus appear very important to the functionality of the streams and in particular to their ability to process allochthonous nutrient inputs in a way that minimizes impacts on the nearshore environment. Prevention of flooding can be accomplished by mechanisms that do not involve elimination of riparian buffer zones and destruction of channel habitat. To maintain water quality and stream functionality, it will be important that these alternative methods of flood control be utilized. Converting natural streams to storm sewers is an unenlightened way to address flooding problems.

Water samples were taken at Waimanalo Stream along the Kahawai tributary and below the confluence of Kahawai and Waimanalo Streams near the mouth of the stream where it discharges into Waimanalo Bay.  Most of the Waimanalo Stream stations were sampled a total of 10-12 times at roughly 3-4 week time intervals during the period February-October, 2002.  Kaneohe Stream sampling was carried out at roughly three-week intervals during the period June-November, 2002.  Most Kaneohe Stream stations were sampled a total of nine times.

Continuous, underwater profiles of ultraviolet (UV), PAR irradiance, and temperature observations with surface reference measurements collected from the R/V LAURENTIAN and other small boats in the Lake Huron in the Great Lakes region from 2022-05-10 to 2022-07-08 (NCEI Accession 0278926)

NOAA Great Lakes Environmental Research Laboratory (GLERL) samples and studies the ecosystem of the lower food web of the Laurentian Great Lakes. This collection contains continuous, underwater ultraviolet (UV), PAR and temperature profiles at 5 stations during the open water season in Lake Huron in 2022. The measurements were collected using a Biospherical Instruments Inc. PUV-2500 submersible, multichannel, profiling, ultraviolet radiometer and PUV2510 reference radiometer attached to the ship during profile collection. UV measurements are in units of microwatts per square centimeter at wavelength (ÂµW/(cmÂ²nm)), PAR measurements are in the units of microEinsteins per square centimeters per second (ÂµE/(cmÂ²sec)) and temperature are in the units of degrees Celsius. Chlorophyll measurements were collected with the instrument, but not included in this data package because the instrument was not calibrated for these locations. The instrument was calibrated for dark offsets as described in the instrument manual on each day the instrument was deployed.

Two summary tables are included in this accession summarizing the attenuation coefficients (Kd) and the 1% attenuation depth. The attenuation coefficients (Kd) were calculated as the slope of the linear regression of the natural logarithm of the ratio_uv versus depth, as described by Kirk (1994). The 1% attenuation depth was calculated using the Kd and intercept from the linear regression of the natural logarithm of the ratio_uv versus depth as: (ln(0.01)-Intercept)/Kd. Only data above 1% of the ambient irradiance were used in these calculations.

Blank cells indicate no data.

The data table column headings and units are described in detail in the data dictionary file named ânoaa-glerl-uv-data-dictionary-2022.csvâ. File formats included in this data package are .csv and jpg.

This dataset contains the bulk density and pore water, sediment texture and composition data from sediment cores collected aboard R/V Weatherbird II cruises WB-0812 and WB-0813 in the northern Gulf of Mexico (nGoM) from 2012-08-14 to 2013-08-21. These data were generated for selected core sub-samples at 2mm sampling intervals for âsurficial unitâ and 5mm sampling resolution intervals to the base of cores. For the bulk density and pore water data, sediment cores were collected on board the R/V Weatherbird II cruise WB-0812 in the nGoM from 2012-08-14 to 2012-08-16. It reports measurement of sediment sample wet weight (g), dry weight (g) and percent pore water. Bulk density is the dry weight per sampling volume expressed as g/cm3. Whereas, sediment texture and composition data were collected aboard R/V Weatherbird II cruise WB-0813 in the nGoM from 2013-08-20 to 2013-08-21. Sediment texture values were expressed as percent gravel, sand, silt, and clay. Percent of mud can be calculated by combining percent silt and clay. Sediment composition was expressed as percent total organic matter (TOM) measured by loss on ignition (LOI), percent carbonate content measured by acid leaching, and the percent insoluble residue (IR), which was likely dominated by terrigenous clastic (land-derived) sediment sources.

Synoptic Monthly Gridded WOD Absolute Geostrophic Velocity (SMG-WOD-V) (January 1945 - December 2014) with the P-Vector Method (NCEI Accession 0146195)

The SMG-WOD-V dataset comprises synoptic monthly global gridded fields of absolute geostrophic velocity inverted from the synoptic monthly gridded WOD temperature and salinity fields (NCEI Accession 0140938) using the P-vector method. It provides monthly varying velocity field that is dynamically compatible to the SMG-WOD (T, S) fields. The SMG-WOD-V has the same spatial resolution and temporal variation as the SMG-WOD (T, S) fields, but does not cover the equatorial zone (5oS â 5oN) due to the geostrophic balance being the theoretical basis for the P-vector inverse method.

Bathythermograph (XBT) data from PRUDENTIAL OCEANJET in the North Atlantic Ocean from 1968-04-02 to 1968-08-09 (NCEI Accession 7300612)

This dataset includes bathythermograph (XBT) data from PRUDENTIAL OCEANJET in the North Atlantic Ocean from 1968-04-02 to 1968-08-09.

Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) format.

The C116/C118 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data record was comprised of pairs of temperature-depth values. Unlike the MBT Data File, in which temperature values were recorded at uniform 5 m intervals, the XBT data files contained temperature values at non-uniform depths. These depths were recorded at the minimum number of points ("inflection points") required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Prior to July 1994, XBT data were routinely processed to one of these standard types. XBT data are now processed and loaded directly in to the NODC Ocean Profile Data Base (OPDB). Historic data from these two data types were loaded into the OPDB.

Experimental studies of influence of hydrogen sulfide on species of eelgrass (Zostera japonica and Zostera marina) in Padilla Bay, coastal waters of southeast Alaska, from 2013-06-01 to 2013-09-30 (NCEI Accession 0137907)

Two species of eelgrass can be found in Padilla Bay, Washington (Zostera japonica and Zostera marina) and act as a bioindicators of ecosystem health. Many factors can contribute to the status of an eelgrass bed, including light, temperature, salinity, and nutrients. However, following several cases of seagrass die-off events worldwide, another factor is suspected to contribute to eelgrass health: pore-water sulfide. This study examined the relationships between Z. japonica, Z. marina, and pore-water sulfide in Padilla Bay and the effects of elevated pore-water sulfide concentrations on eelgrass. Forty sites were surveyed for eelgrass shoots and sulfide concentration profiles were measured at depths of 0 to 12 cm. A correlation was expected between eelgrass and the inventory of sulfide during August and September due to increased temperature and increased bacterial respiration as a result of higher quantities of organic matter accumulation. While the data hinted at patterns between eelgrass density and sulfide, there were no significant correlations found between Z. japonica and Z. marina and the inventory of sulfide from June 2013 through September 2013. This is perhaps due to relatively low concentrations of sulfide at the study sites and documented eelgrass tolerance to the concentration range, as well as the overall health of eelgrass in this location.

To further examine the relationship between eelgrass and sulfide, Zostera japonica and Zostera marina were grown in sediment amended with sulfide in an outdoor laboratory tank to study growth response and photosynthetic yield. Eelgrass shoots were grown for four weeks under different sulfide manipulations and shoot growth was recorded weekly. Quantum efficiency of PSII in eelgrass shoots was measured by PAM fluorometry at the conclusion of the experiment. The growth rates of Z. japonica and Z. marina were significantly reduced in treatments with elevated sulfide concentrations. Manipulated concentrations of pore-water sulfide resulted in significantly lower growth rates among Z. japonica shoots treated with moderate and high levels of sulfide. The decrease in growth in both species suggests that elevated levels of pore-water sulfide have an impact on eelgrass in Padilla Bay. The average photosynthetic yield of the shoots for Z. japonica and Z. marina was lower in shoots treated with sulfide, although this difference was not statistically significant, suggesting the drop in growth was not due to chloroplast damage.
