Overview
The Aanderaa 5218 Wave & Tide Sensor is a compact, fully integrated sensor for measuring wave and tidal conditions. The sensor is designed to be mounted on the Aanderaa SeaGuardII top-end plate or in other measurement systems using the RS-232 interface.
Applications
The sensor application areas are in fixed installations, either deployed in a seabed installation in shallow waters or mounted onto a fixed structure in the upper water column. Typical applications for the sensor are measuring waves and tides in ports and harbors, marine operations, weather forecasts, and climate studies.
Mechanics
The tide measurement is an average of the hydrostatic pressure measured over a time period of 10 seconds to 8 minutes (integration time configurable by the user). The update interval is between 1 second and 255 minutes. The wave measurements are based on the pressure time series measured over a time period of 64 seconds to 17 minutes (configurable by the user). The update interval is between 1 second and 255 minutes.
Parameters
The wave and tide sensor output parameters are Pressure, Tide Level, Tide Pressure, Temperature, Significant wave height, Maximum wave height, Mean period, Peak period, Energy wave period, Mean zerocrossing period, Wave steepness, and irregularity of sea-state. Since all calibration and temperature compensation data are stored inside the sensor, the parameters are, by default, presented directly in engineering units without any external calculation. The sensor also provides raw data on the pressure and temperature measurements.

Climate Change and Microplastics: Monitoring Lake Champlain
Most people go to Lake Champlain for its exceptional views and thrilling boating, but it’s also home to a wide variety of interesting aquatic research projects. From studying microplastics to thermal dynamics of the lake, Timothy Mihuc, director of the Lake Champlain Research Institute (LCRI) at the State University of New York at Plattsburgh (SUNY Plattsburgh), has spent his career studying aquatic ecosystems. As an aquatic biologist, he’s the main investigator on Lake Champlain’s research studies while also managing their grants, employees, and their hands-on buoy work. Over the years, LCRI has received a number of environmental grants that aid in its monitoring research.

Current Monitoring after the Francis Scott Key Bridge Collapse
On March 26th, according to The Baltimore Sun , a 984-foot, 112,000-ton Dali lost propulsion and collided with a support column of the Francis Scott Key Bridge, collapsing the structure. Soon after the event, search and rescue, salvage crews, and other emergency responders were mobilized after the collision. As salvage efforts progressed in early April, NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) responded to a request for real-time tidal currents data and deployed a current monitoring buoy—CURBY (Currents Real-time BuoY)—into the Patapsco River north of the Francis Scott Key Bridge.

Soundscapes of the Solar Eclipse: Citizen Science Supporting National Research
On April 8, 2024, millions of people around the world had their eyes glued to the sky to witness a historic cosmic event. The total solar eclipse captured the headlines and the minds of many who became eager to gaze at the heavens as the sky went dark for a few minutes. However, not everyone used their sense of sight during the eclipse, some were listening to the sounds of the natural world around them as the light faded from above. The Eclipse Soundscape Project is a NASA-funded citizen science project that focuses on studying how the annular solar eclipse on October 14, 2023, and the April 8, 2024 total solar eclipse impacted life on Earth. The project revisits an initiative from the 1930s that showed animals and insects are affected by solar eclipses.
