National Whale and Dolphin Watch 2018 is most successful yet! (Watch Video)
As the National Whale & Dolphin Watch concludes for another year, organisers are calling the 2018 event the most successful yet with an unprecedented variety of whale and dolphin species recorded around the UK during last week. Thirteen species and more than 500 sightings have been reported, and sightings continue to stream in.
“This looks like being the best National Whale & Dolphin Watch event of the last two decades,” reported Dr Chiara Giulia Bertulli, organiser of this year’s national event for the UK national research charity, Sea Watch Foundation.
The 2018 National Whale and Dolphin Watch event involving thousands of volunteers from all around the British Isles, conducted between 28th July and 5th August, has revealed the striking biodiversity of Britain’s Whales, Dolphins and Porpoises.

This summer has seen a good number of humpback whale sightings all around the UK, with individuals popping up this last week in the North Sea off the Aberdeenshire coast and off Flamborough Head in Yorkshire. This species is making a noticeable come-back after many decades of exploitation in the North Atlantic.
“However, the most extraordinary sighting from this year’s Watch week”, adds Chiara, “was surely the Sowerby’s beaked whale which live stranded in the shallow waters of Belhaven in East Lothian, Scotland, on July 29th. This year also saw the addition of the striped dolphin, which in Britain and Ireland, is very rare, seen occasionally off the Atlantic coasts mainly in the south-west of Ireland. This species of warm temperate seas came to the shore at Pendine in South Wales on July 31st.”

At the time of writing, a total of 527 sightings have been submitted after the 9-day event. With regards to number of species recorded, results show that records at this stage are up 50% on last year. Cetacean data collection is strongly weather dependant. Factors such as sea state, swell height and visibility to the horizon affect how easily animals can be detected during a watch. Heavy rain and wind can even cause watches to be cancelled altogether.
For these reasons, every year, the volunteers rely heavily on good weather conditions for the success of National Whale and Dolphin Watch. Like previous years, this year’s event was scheduled over nine days to increase the chances of coinciding with a favourable weather window. The weather forecast at the beginning of the event was very poor with frequent showers and strong winds around the country which forced several watches to be cancelled and to be rescheduled to this past weekend. However, once the weather stabilized and the temperature increased the number of sightings increased dramatically and it showed.

Possible explanations for this summer’s high number of cetacean species sighted during this year’s event are the good stable weather recorded this summer, with high temperatures which brought in warmer water species like striped dolphin, and created the conditions for plankton fronts to develop, attracting shoals of fish and in turn, whales and dolphins.
“We are seeing a general longer term trend,” adds Chiara, “for warm water species to be extending their range further north – species like the short-beaked common dolphin and the Risso’s dolphin as well as the striped dolphin. Since a greater number of species live in warm waters, the effects of climate change can actually be positive at mid latitudes such as around the British Isles.”
“We should still be a little cautious,” says Dr Peter Evans, Director of the Sea Watch Foundation. “Although new species of cetaceans have been added recently to the British list of mammals, there are more northern species that we could lose from our fauna – species like Atlantic white-sided dolphin and white-beaked dolphin, and the problem with tropical and warm temperate species entering our seas is that they face a much wider range of human pressures along the industrialised coastlines of northern Europe.”

Renowned anti-whaling activist Paul Watson has been released from custody in Greenland after spending five months in detention. Denmark’s Justice Ministry rejected Japan’s request for his extradition, citing insufficient guarantees that his time already served in custody would be credited against any potential sentence.
The 74-year-old Canadian-American was arrested on July 21 in Nuuk, Greenland’s capital, when his ship docked to refuel. His arrest was based on a 2012 Japanese warrant related to a 2010 encounter in Antarctic waters. Japan alleged Watson obstructed operations and caused damage to a whaling research ship during efforts to disrupt illegal whaling. Watson has consistently denied these claims, maintaining his commitment to marine conservation.
Denmark, which oversees extradition matters for Greenland, concluded that while the legal conditions for extradition were met, the lack of assurances from Japan regarding time-served credit made extradition untenable.
In a video shared by his foundation, Watson expressed gratitude and relief, saying, “After five months, it’s good to be out… and good to know they’re not sending me to Japan.” He added that the most difficult part of his time in custody was being separated from his two young sons.
Watson is a pioneering figure in marine conservation, known for founding the Captain Paul Watson Foundation in 2022 after decades of activism with the Sea Shepherd Conservation Society. His bold efforts to defend marine life have earned him widespread support, including from celebrities and conservationists. His work has also been featured in the acclaimed reality TV series Whale Wars.
Watson’s lawyer, Jonas Christoffersen, praised the decision, stating, “We are happy and relieved that Paul Watson is now free.” He added that Watson is eager to reunite with his family and continue his vital work.
The arrest occurred while Watson’s vessel, the M/Y John Paul DeJoria, was en route to the North Pacific with a team of 26 volunteers to intercept a Japanese whaling ship. His foundation described the arrest as politically motivated and emphasized that Watson’s actions were focused on ending illegal whaling practices.
Japan resumed commercial whaling in 2019 after leaving the International Whaling Commission, asserting that whale meat is a cultural tradition. Conservationists, however, continue to challenge these practices, highlighting their impact on marine ecosystems.
Despite the challenges, Watson remains steadfast in his mission to protect marine life and bring attention to whaling practices. His dedication to ocean conservation has made him a globally respected advocate for the environment.
