On board Silurian

Crew of the SilurianSilurian is HWDTs research and education vessel.

Most weeks April through October she is either monitoring the waters of the west coast of Scotland for whales, dolphins, and porpoises, or serving as a floating classroom for one of the many Argyll island primary and secondary schools.

Read the log below to find out what Silurian and her crew have been up to each week and all about the whales, dolphins and porpoises they spot!  To find out about the latest marine life sightings spotted elsewhere, click here.

WWF Donors Week – 10th September

Our first morning on the boat, we expected a cruel 6.30am awakening but Peter very kindly allowed us a lie-in. Scottish oats did the trick (though they didn’t have to last us for very long as Peter was making bacon and egg rolls by 11am!).

We left Glenelg with James in the crows nest and didn’t have to wait long for our first Porpoise sighting. You don’t get much more than a glimpse of the Porpoises dorsal fins and curved backs, but it still set the day off optimistically. We continued our survey down the Sound of Sleat enjoying the hazy morning sunshine while it lasted, for the weather was set to change. Hundreds of Lion’s Mane Jelly fish floated past the boat, though a bit ugly (and they sting) they are still remarkably fascinating creatures, their destiny set by the wind.
As the sea state picked up with the southerly breeze, our chances of seeing porpoises through the white caps decreased. However, we were still able to detect them with Silurian’s hydrophone, which is towed behind the boat at all times. This underwater microphone ‘listens out’ for porpoise echolocation clicks and shows us when they are in the area. So even if we cannot see them, we can ‘hear’ them instead!

We sailed into Loch Nevis following up reports earlier in the summer of two bottlenose dolphins frequenting this area. Though the dolphins proved elusive we did have some fascinating finds whilst rock-pooling after our excursion to the ‘worlds most remote pub’.

Onwards to Mallaig – and we did see some Porpoises – hurrah! We dropped Cally (HWDT’s project director) off in Mallaig and started to make our way to our final destination for the day - Loch Nanceall in Arisaig. Little did we know the adventure in store as we waved to our friends on the boat ‘Forever Changes’ - Colin Speedie and his partner Lou take Forever Changes all over the Hebrides monitoring Basking Sharks. As we ploughed through the rough seas a plea from Forever Changes came across the airwaves, their gearbox had bust. Forever Changing is a pretty big boat so I was really surprised to see that our Silurian could tow them (at a slow pace albeit!) to our next stop. It took about 1 ½ / 2 hours to get to Arisaig, and great skill was needed to navigate into the shallow and rocky Loch. To be honest I was petrified - I was watching the monitor as Rob expertly guided us in and sure it said we were at a depth of minus 1 metre! Anyway Rob and Peter had us moored up within 15 minuets, Forever Changes were moored up too – all they need to do now is find a new gear box.

Pia and James made a fantastic fish pie, which went down well with wine. I then introduced my fellow boat mates to Rum and orange juice – you have to drink Rum at sea don’t you?

A few of us took the tender to the pub onshore. The wind had died and the journey in the dark was very calm, as we set off Phosphorescent plankton glowed in the water – like zillions of stars in the dark sea, if you ran your hand in the water you could see even more. We had a few drinks with some of the locals and the Crew of Forever Changes and made our way back at about midnight.

One memory I shall take with me of this day at sea is my trip to the toilet after returning from the pub, of course the toilet water is sea water – imagine my surprise to see the Phosphorescent Plankton in the toilet bowl!

Over and out.
