Outdoors

Lovers of the oceans and the life within them have just a few days left to experience "Science and the Sea," an exhibition of photographs by the marine scientist and explorer Gaelin Rosenwaks at the Montauk Lighthouse Oceans Institute that is but a glimpse into the life of an inveterate adventurer, an academic scientist turned storyteller whose career on a given day may see her swimming with blue sharks off Montauk, or hammerheads in the Bahamas, or 45-ton sperm whales off the island of Dominica.

For those with an appreciation of nature or a thirst for paddling, hiking, or biking, there are lots of upcoming activities that promise to be interesting.

Saturday is National Trails Day, and the Friends of the Long Pond Greenbelt invite hiking enthusiasts to a 3.5-mile hike and lunch from 10 a.m. to noon. Participants should take their own food and meet at the Friends' nature center at 1061 Bridgehampton-Sag Harbor Turnpike. Dai Dayton will lead the hike, and can be contacted for questions at 631-745-0689.
