Abstract:
The physical/chemical component of the Maryland Chesapeake Bay Water Quality Monitoring Program consists of data collected at twenty-one stations located in Maryland's Chesapeake Bay mainstem.
Sampling was conducted twice monthly in June, July and August of 2012, and once monthly during the remaining months, for a total of fifteen samplings in the period of 1-Jan-2012 through 31-Dec-2012. Sampling during the first July cruise was limited to physical measurements collected to better assess dissolved oxygen levels in the mainstem deep waters. No samples were collected November through February at eastern and western transect stations, resulting in only ten mainstem flanking station samplings a year.
The water quality monitoring program began in 1984 and is ongoing. The program assesses the water quality by evaluating the levels of nutrients and closely related habitat impacts such as dissolved oxygen and water clarity. One of the main goals of the Chesapeake Bay restoration is to reduce the impacts of excess nutrients on the Bay and these measures provide some of the most direct linkages to management programs that are achieving this goal. The Chesapeake Bay Program jurisdictions have agreed to reduce nitrogen, phosphorus and sediment pollution to the Bay.

Purpose:
The Maryland Department of Natural Resources Chesapeake Bay Water Quality Monitoring Program is part of a cooperative effort between the Federal government and State and local governments in the Chesapeake Bay watershed to assess the status and trends of nutrient and sediment concentrations in Maryland's Chesapeake Bay mainstem.
The information is integrated with data from other Bay water quality stations and living resources monitoring projects and used to understand linkages, temporal variation and long-term trends.
Water quality data are used to refine, calibrate and validate Chesapeake Bay ecological models. The models are used to develop and assess water quality criteria with the goal of removing the Chesapeake Bay and its tidal rivers from the list of impaired waters.

Attribute_Accuracy_Report:
QUALITY ASSURANCE/QUALITY CONTROL Maryland Department of Natural Resources followed specific procedures to ensure that the Mainstem component of the Chesapeake Bay Water Quality Monitoring Program design was properly implemented and managed with sufficient accuracy, precision and detection limits. Accuracy (closeness to the true value) of collected data was controlled and assured by proper use, calibration and maintenance of both field and laboratory equipment for the measurement of physical and chemical parameters.
The procedures to control and assure the accuracy of field measurements involved the calibration of field instruments, the verification of calibrations, and equipment maintenance. Most of the details of how data acquired with YSI sondes were quality assured and quality controlled are described in the process description elements in the Lineage portion of this metadata record.
Daily quality control checks which included the running of blanks and standards were used to control and assure laboratory accuracy.
Accuracy of Chesapeake Biological Laboratory, Nutrient Analytical Services Laboratory (CBL NASL) results was also assessed through DNR's participation in the Chesapeake Bay Coordinated Split Sample Program (CSSP) a split sampling program in which five laboratories involved in Chesapeake Bay monitoring analyze the coordinated split samples. CSSP was established in June 1989 to establish a measure of comparability between sampling and analytical operations for water quality monitoring throughout the Chesapeake Bay and its tributaries. DNR followed the protocols in the Chesapeake Bay Coordinated Split Sample Program Implementation Guidelines (EPA 1991) and its revisions. Split samples were collected quarterly. Results were analyzed by appropriate statistical methods to determine if results differed significantly among labs. If a difference occurred, discussions began regarding techniques and potential methods changes to resolve discrepancies.
January 2012 - Compensating for strong currents while raising the meter, water quality sonde, can result in the need to extend more cable in order to position the meter at a required depth. Greater meter scope than normal was required at station CB4.4.
February 2012 - A note in the log indicated that on the morning of 15-Feb-2012 samples placed in the freezer the previous afternoon, were not frozen. The need for greater meter scope than normal was observed at stations: CB5.1 and CB4.4.
March 2012 - Meter scope greater than normal was required at stations: CB5.3, CB5.2, CB5.1, CB4.4 and CB4.1E.
May 2012 - Water column readings were re-checked at 3.0m and conductivity was deemed unstable at 5.0m at station CB3.2.
June 4-6, 2012 - Strong currents resulted in the need for greater meter scope at stations: CB5.3, LE2.3, CB5.2, CB5.1, and CB4.4. Surface and 1.0m water samples were collected from the same bottle at stations CB5.2 and CB4.4.
June 25-27, 2012 - A ship passed nearby while samples were collected at station CB4.4. At station CB4.3C, meter scoping and unstable readings between the depths of 8.0m and 10.0m were noted. An unstable conductivity reading at 6.0m was recorded at station CB3.3C. Readings at station CB3.2 were also described as unstable.
July 23-25, 2012 - An H2S odor was observed in station LE2.3 bottom and below pycnocline water samples. H2S odor was also noted in bottom sampled collected at stations: CB4.1C and CB3.3C. At station CB4.1E meter scoping was needed and the readings between 16.0m and 19.0m were unstable.
August 6-8, 2012 - H2S odors were noted in bottom and below pycnocline water samples collected at stations: CB5.1 and CB5.2. Bottom water samples at stations: LE2.3, CB4.4, CB4.3C, CB4.2C and CB4.1C also smelled of H2S. At station CB4.3W, the air temperature reading might have been elevated due to exhaust from an air conditioner. Station CB3.2
August 20-22, 2012 – A very slight H2S odor was observed in station CB4.4 bottom sample water. A cargo vessel passed nearby while sampling was under way at station CB3.2.
September 2012 - The passage of a ship was noted while sampling station CB5.3.
December 2012 – A station CB3.2 log note observed that specific conductance changed and, that the below pycnocline sample should have been collected from 4.0m depth.
Logical_Consistency_Report:
For logistical reasons, station LE2.3, a Potomac River sampling project station, is routinely sampled during Chesapeake Bay mainstem sampling cruises.
January 2012 - The station CB3.2 surface sample was collected at 1.0m due to pitching and rolling sea conditions..
February 2012 - Surface and 1.0m water samples were collected from the same bottle at station CB4.4.
March 2012 - Surface and 1.0m water samples were collected from the same bottle at stations: CB5.3, CB5.1, and CB4.4.
April 2012 - No known issues.
June 4-6, 2012 - Surface and 1.0m water samples were collected from the same bottle at stations: CB5.2 and CB4.4.
June 25-27, 2012 - Surface and 1.0m water samples were collected from the same bottle at stations: CB4.3, CB3.3C and CB3.2.
July 9-11, 2012 - The purpose of the cruise was to learn about bottom dissolved oxygen conditions. The only samples collected were water quality sonde measurements taken throughout the water column at stations.
August 2012 - RV Kerhin’s freezer was replaced. There was less storage space in the new freezer. Frozen water samples, normally stored aboard overnight, were removed to a freezer on land.
September 2012 – Mainstem surveys are usually conducted over the course of three consecutive days. In September 2012, heavy weather conditions and ship time limitations resulted postponing sampling scheduled for 18-Sep-2012 and 19-Sep-2012. On 20-Sep-2012, the remaining mainstem center stations were sampled. It was not possible to sample the rest of the Eastern and Western flanking stations. Frozen water samples, normally stored aboard overnight, were removed to a freezer on land.
October 2012 - Surface and 1.0m water samples were collected from the same bottle at stations: CB5.3, LE2.3, CB5.2, CB5.1, CB4.4, CB4.3E, CB4.3C, CB4.2W, CB4.2C, CB4.2E, CB4.1E, CB4.1C, CB4.1W, CB3.3E, CB3.3C and CB3.3W. The station CB4.2E bottom sample was collected from 7.0m instead of 8.0m which is the usual bottom sample depth for the station. Frozen water samples, normally stored aboard overnight, were removed to a freezer on land.
November 2012 - Surface and 1.0m water samples were collected from the same bottle at stations: CB5.2, CB5.1, CB4.4, CB4.3C, CB4.2C, CB5.3 and CB5.2. Frozen water samples, normally stored aboard overnight, were removed to a freezer on land. December 2012 - Frozen water samples, normally stored aboard overnight, were removed to a freezer on land.

Process_Description:
SONDE CALIBRATION and POST-CALIBRATION
The Yellow Springs Instrument (YSI) 6000 data sondes were maintained and calibrated before and after each cruise in accordance with manufacturer's recommendations.
WATER COLUMN PROFILE SAMPLING PROTOCOLS:
A profile of temperature, specific conductance, dissolved oxygen, and pH was obtained from the water column by deploying the data sonde at 0.5 m, 1.0 m, 2.0 m and 3.0 m depth intervals below the surface. Thereafter readings were taken at 2.0 m intervals and at the bottom. Tributary bottom equals total depth minus one meter (not rounded). If the change in dissolved oxygen exceeded 1.0 mg/L or if the change in specific conductance equaled or exceeded 1,000 micromhos/cm over any 2.0 m interval, readings were taken at 1.0 m intervals between these two readings. For total depths less than or equal to 10.0 m, readings were taken at 1.0 m intervals.
GRAB SAMPLING DEPTH PROTOCOLS:
At stations where two depths were sampled, collections were taken at 0.5 m below the surface, and 1.0 m above the bottom. If the station total depth was equal to 1.5 m, the bottom sample was also collected at 0.5 m. Great caution was exercised when taking bottom samples; if the bottom was disturbed and bottom sediments appeared to have been included, the sample was dumped out and collected after the sediments had settled. Alternately, the sample was collected slightly higher in the water column and the new bottom sample depth was noted.
At stations where 4 depths were sampled and a pycnocline existed, collections were taken at 0.5 m below the surface, 1.5 m above the upper boundary of the pycnocline, 1.5 m below the lower boundary of the pycnocline, and 1.0 m above the bottom.
At stations where 4 depths were sampled and there was no discernable pycnocline, samples were taken at 0.5 m below the surface, at the closest profile depth one third the distance from the surface to the bottom, at the closest profile depth two thirds the distance from the surface to the bottom, and 1.0 m above the bottom.
SECCHI DEPTH:
Water transparency was determined, to the nearest 0.1 m using a 20-cm standard Secchi disc lowered into the water column with a calibrated rope. Observations were made on the shady side of the sampling location.

VERIFICATION AND DATA MANAGEMENT:
Each month DNR Tawes Office and Field Office personnel conduct data QA/QC procedures. All of the water quality calibration "grab" sample data are plotted. Outliers and anomalous values are thoroughly researched. Staff members compare unusual values to historic values from the site and values from nearby sites. Weather events are considered, event logs are reviewed and CBL analytical laboratory staff members and DNR field staff members are consulted regarding possible legitimate causes for outlying values. In cases where values are not considered to be legitimate, they were masked in the published dataset with the approval of the field staff and the Quality Assurance Officer.
