A person wearing a beige beanie and glasses adjusts an ultrasonic water level sensor mounted on a post. The sensor has a yellow sticker with a sailboat logo and text for Woods Hole Oceanographic Institution. A white solar panel is attached above the sensor, and a coiled rope is visible nearby. The background shows a clear blue sky and blurred trees.

A man in a white beanie and orange safety vest kneels on a dock, adjusting an ultrasonic water level sensor mounted on a post. The bright blue sky and water are in the background. Another man in a brown jacket stands behind, observing.

A small solar panel is mounted on a metallic box attached to a pipe. The box has coiled cables secured on its side and is positioned near a wooden pier with weathered posts. The background shows water and additional wooden structures.

Connecticut has over 600mi of coastline, but only three tide gauges to track sea level rise.

To help the state understand how and where flooding happens, WHOI scientists are partnering with communities to install low-cost sensors.

Close-up of a fish eye, displaying iridescent colors with green, blue, and silver hues against a speckled skin background. The eye's circular pupil is surrounded by a vibrant, reflective iris, and delicate fish scales are visible on the periphery.

A translucent fish with a large eye and fan-like fins swims against a dark background. Its body is iridescent with hints of purple and silver.

Oh my! What big eyes you have!

Juvenile bluefin driftfish can be found near the surface, where large eyes help them navigate and spot small prey. As adults, bluefin driftfish venture to deeper waters to find food and avoid predation, where their large eyes improve their ability to detect prey.

During the winter, these penguins huddle together, weathering storms as a community. Sound familiar?

As this week’s Nor’easter reminded those of us in New England, when nature presents a challenge, adapt, layer up, and lean on each other.

A polar bear is leaping across icy, blue water between snow-covered ice floes. The bear appears mid-air, with its front paws extended forward. The surrounding landscape is a vast, icy terrain.

A polar bear stands on a piece of floating ice surrounded by vast, broken ice sheets and open water in an Arctic landscape.

A large red and white icebreaker ship is stationed on a vast expanse of ice under a clear blue sky. Several people in red suits are visible walking on the ice toward the ship, with vehicle tracks and a yellow barrel in the foreground.

Did you know you can tell the history of an iceberg based on its shape?

1: A jagged berg means the ice has likely never been underwater
2: A diagonal ridge, the iceberg has likely rolled
3: Rounded surfaces mean the top was underwater at one point
