String acquisition_description
"Bi-weekly water sampling and in situ measurements were performed at fixed
sampling stations.\\u00a0 In situ measurements were\\u00a0performed throughout
the water column in 0.5 meter depth increments.\\u00a0 Parameters measured
include: temperature, salinity, specific conductivity, dissolved oxygen (DO),
pH, chlorophyll fluorescence, photosynthetically active radiation (PAR),
turbidity, and barometric pressure.
Methods
Water sampling was conducted bi-weekly. When collection was split over two
days, a single date was used based on the upstream or majority stations.
Stations were selected to cover the entire length of the Neuse River Estuary
from Streets Ferry Bridge (Station 0) to the mouth of the estuary where it
flows into Pamlico Sound.\\u00a0 When possible, efforts were made to select
locations with key stationary features (channel markers, buoys and land
markers) to allow easy station identification in the field.
Surface water samples were collected by submerging 10 liter high-density
polyethylene containers just below the water surface or by filling the
containers with surface water collected from bucket casts.\\u00a0 Bottom water
samples were collected with a horizontal plastic Van Dorn sampler. Starting
December 2007, all samples collected with diaphragm pump and a weighted,
marked hose. All containers were kept in dark coolers at ambient temperature
during transport to the laboratory.\\u00a0 All filtration was done within a few
hours of collection and when conditions permitted, on board the research
vessel.
Prior to the 09/13/2000 sampling date, in situ measurements were performed at
discrete depths using a Hydrolab Data Sonde 3 equipped with a multiprobe and
SVR3 display logger.\\u00a0 Beginning on the 09/13/2000 sampling date, in situ
measurements were performed at discrete depths on the sunlit side of the
research vessel using a Yellow Springs Instruments (YSI Incoporated, Ohio)
multiparameter sonde (Model 6600 or 6600 EDS-S Extended Deployment System)
equipped with a YSI conductivity/temperature probe (Model 6560), a YSI
chlorophyll probe (Model 6025), a YSI pH probe (Model 6561 or 6566), a YSI
pulsed dissolved oxygen probe (Model 6562), a self cleaning YSI turbidity
probe (Model 6026 or 6136), and beginning on the 07/30/2003 sampling date, a
flat Li-Cor sensor (UWQ-PAR 6067).\\u00a0 The YSI sonde was coupled to a either
a YSI 610 DM datalogger or a YSI 650 MDS Multi-parameter Display System
datalogger.\\u00a0 In situ measurements were performed at the surface
(approximately 0.2 meters) and at the bottom of the water column
(approximately 0.5 meters from the sediment layer).\\u00a0 These data are
included in the worksheet titled \\\"NRE Dataset.\\\"\\u00a0 In situ measurements
were also performed throughout the water column in 0.5 meter depth
increments.\\u00a0 These data are included in the worksheet titled \\\"NRE YSI
Profiles.\\\"\\u00a0 The data were stored on the datalogger and downloaded to
Ecowin software upon return to the laboratory.
Distance (in river kilometers) was calculated using ESRI ArcGIS
software.\\u00a0 Distances were calculated using projected station locations
(North Carolina State Plane 1983 meters projection).\\u00a0 Distances from
station 0 through 30 (upper river stations) were measured along the main
channel of the river. Distances from stations 30 to 180 were measured as
straight lines between stations";

"NSF Award Abstract:
Climatic perturbations by drought-flood cycles, tropical storms, and hurricanes are increasingly important in Mid-Atlantic estuaries, leading to ecosystem-scale responses of the plankton system with significant trophic implications. Recent observations support an emerging paradigm that climate dominates nutrient enrichment in these ecosystems, explaining seasonal and interannual variability of phytoplankton floral composition, biomass (chl-a), and primary production (PP). This project will evaluate this paradigm in the two largest estuaries in the United States, Chesapeake Bay (CB) and Albemarle-Pamlico Sound-Neuse River Estuary (APS-NRE) by quantifying responses to climatic perturbations. This project will: (1) resolve long-term trends of plankton biomass/production from high variability driven by climatic forcing, such as drought-flood cycles that generate significant departures from the norm; (2) quantify the role of episodic wind and precipitation events, such as those associated with frontal passages, tropical storms, and hurricanes, that evoke consequential spikes of biomass/production outside the resolution of traditional methods. The field program will focus on event-scale forcing of phytoplankton dynamics by collecting shipboard, aircraft remote sensing, and satellite (SeaWiFS, MODIS-A) data, analyzing extensive monitoring data for CB and APS-NRE to develop context, and quantifying effects of climatic perturbations on phytoplankton dynamics as departures from long-term averages. The rapid-response sampling will be paired with numerical simulations using coupled hydrodynamic biogeochemical models based on the Regional Ocean Modeling System (ROMS). This combination of observations and modeling will be used to explore mechanistic links and test empirical relationships obtained from field data.
Intellectual Merit. Drought-flood cycles, tropical storms, and hurricanes are occurring at increasing severity and frequency, exerting significant pressures on land margin ecosystems. Research and monitoring in these ecosystems has focused singularly on eutrophication for nearly five decades. Recognition of climatic perturbations as the underlying cause of phytoplankton variability represents a significant departure from this singular focus. This project will combine observations and modeling to significantly extend our knowledge of how climate regulates phytoplankton dynamics in estuaries. Progress in calibrating and validating hydrodynamic biogeochemical models with data collected in CB and APS-NRE by this project will lead to predictive capabilities thus far unattained, allowing us to evaluate the paradigm that climatic perturbations regulate phytoplankton dynamics in estuaries.
Broader Impacts: Addressing the effects of climatic perturbations on phytoplankton dynamics in estuaries with a combination of data collection, analysis, and mechanistic modeling has societal benefits for scientists and resource managers. Applications in addition to ?basic? science include the consideration of climatic forcing in designing effective nutrient management strategies. Specific impacts include: (1) quantifying the effects of climatic perturbations on planktonic processes for important estuarine-coastal ecosystems; (2) extending empirically-based water quality criteria forward by enabling predictions of floral composition, chl-a, and PP in changing climate conditions; (3) combining observations and mechanistic models to support scenario analysis, allowing us to distinguish long-term trends from variability imposed by climate. This project will offer a graduate course in physical transport processes and plankton productivity that will benefit from this research, support two Ph.D. students, and train undergraduates in NSF REU and minority outreach programs at HPL-UMCES and IMS-UNC. The main products will be peer-reviewed publications and presentations at scientific meetings. The three PIs maintain active web sites that will be used to distribute results and data.

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
