What is Real-time Data? • Data that is being collected by scientists, students, teachers, or trained citizens from an actual site. • Some data is up to the minute such as buoy data. • Data can be used to analyze and answer questions about rivers, estuaries, and oceans.
Using Real-time Data The purpose is to observe the abiotic factors that affect ecosystems and determine water quality of aquatic and coastal ecosystems.
Where can I find Real-time data? • Ocean Observing Systems http://marine.rutgers.edu/outreach/rtd/resources4.htm • National Estuarine Research Reserve System http://cdmo.baruch.sc.edu/

Research Question • Does bottom salinity vary or does it stay relatively stable? • View a number of graphs; not just one or two. • Look at one location first.
Bottom Salinity Year???http://carocoops.org/carocoops_website/buoy_graph.php?interval=1_day
Could you answer the original question? • Is it too vague? Yes. • Could you give a range of salinities? • Could you look at surface salinities to see if that changes more. You could but that is another question altogether. Keep focused.
Research question: • Does the dissolved oxygen in the Potomac River ever reach levels detrimental to aquatic life? • First, find out what levels are acceptable and at what numbers fish will die. Then check out some of the data for the Potomac River.

The previous slide does not give enough information to draw any conclusions. Think about how much data is necessary to answer questions. • These slides are designed to get you thinking and started but are not part of a complete project. • Follow the Rubric and instructions given in class.
Nickname:Green Harbor River 1 Serial Number (SN):2008485 Model:HOBO U30 Station - GSM Firmware Version:1.008
Green Harbor River, Marshfield Tide Station Installed – With support from the MA Corporate Wetlands Restoration Partnership, the ERM Foundation, the UMASS-Boston Coastal Environmental Sensing Network, MA Audubon, and the Town of Marshfield, CZM-WRP has installed a semi-permanent tide monitoring station along the Green Harbor River in Marshfield. The solar-powered, high-tech station continuously reads tide height, water temperature, and salinity. Every 30 minutes, a telemetric control box dials a cell phone number and data is uploaded to the system, where it can be viewed on the world-wide web in near real-time. The tide station will allow town officials, local landowners, and other project partners to keep a close eye on the Green Harbor River tidal patterns, which are expected to change gradually after the town installs a new, adjustable tide gate within the Green Harbor Dike along Route 139.

When was the data logger in the river? What else can you determine from the graph?
What was the water temperature in Green Harbor on September 30, 2010?
What was the water temperature at Brant Rock? These loggers were worn around the neck until deployed.
