2023 Marine Interns Blog Week 4: National Whale and Dolphin Watch

We finished National Marine Week by joining Lincolnshire Wildlife Trust’s Coastal Wardens and participating in the National Whale and Dolphin Watch, in partnership with Sea Watch Foundation.

Every year, Sea Watch Foundation hold a week-long National Whale and Dolphin Watch (NWDW) in order to gain a better overview of the distribution of cetaceans (dolphins, whales and porpoises) within UK and Irish waters. Although cetaceans are the focus of this week, Sea Watch Foundation collect data on cetaceans, seals, sharks, turtles, sunfish and tuna year-round, so if you spot any of these animals remember to submit your findings to Sea Watch Foundation via their website or app!

DAY 1:

For our first day participating in the NWDW, we were based at the North Sea Observatory, Chapel St Leonards. I had never visited the North Sea Observatory before, and it definitely didn’t disappoint! The building opened in 2018, and is purpose-built to watch marine wildlife, with large windows allowing you to look out to sea. We joined Richard Doan, one of the Coastal Wardens for Lincolnshire Wildlife Trust, who helped us to identify many of the species we saw. Unfortunately, we saw no cetaceans, but plenty of seabirds and several grey seals paid us a visit. The most notable seabirds we saw were; common terns, sandwich terns, arctic skua, razorbills, and common scoater. Although sad not to see any cetaceans, it was amazing to see such a diversity of seabird species and it helped us to realise the importance of the east coast as a migratory route for these birds.

Shells

During our lunch break, we also took a walk along the coast, and were stunned by the variety of shells washed up on shore! There were scallops, oysters, tellins, razor shells and plenty of other bivalves to be seen. We also saw plenty of whelk shells (which have a whorl/ spiral shape to them) – accompanied by washed up whelk egg capsules too! It’s amazing that you can find such a diversity of marine matter on the beach, and allows you to visualise the diversity of organisms living on our sea bed.

DAY 2:

Our second day of the NWDW was spent a little further north at Anderby Creek, with coastal warden Dave Miller. We based ourselves up by the ‘round and round house’, an art installation which serves as a lookout point, to get a good view of the sea. It was a much windier day, which made our job more difficult as the waves were creating crests – which are similar in appearance to the breaks that whales, dolphins and porpoise make in the sea when they come up for air. We didn’t let this dishearten us though, and stayed on lookout, sheltering inside the round and round house when the rain got heavy and the wind picked up.

Similarly to day 1, we saw a few grey seals and a bunch of interesting seabirds – which Dave helped us to identify. Despite our efforts, we weren’t lucky enough to see any cetaceans, but you might be! Harbour porpoise are the most commonly sighted cetacean in these waters, so keep your eyes peeled for them if you’re visiting the east coast.

Thank you to Richard and Dave for teaching us a bit about the North Sea’s marine wildlife. We thoroughly enjoyed our visit to the coast, and hope to be back out sea watching soon!
