...so hope this is ringed and previous (other) is Harp.
These are also Harp - lack of black face being due to young age. Excellent photo showing their typical behaviour too - swimming on their back, and 'bottling' right out above the surface.
Cracking trip report, and some brilliant photos. I've just returned from Svalbard, though as part of a marine mammal survey. We only covered the western coast of Spitsbergen as far north as Magdalena Bay, but still came up trumps with Walrus and a single Polar Bear. We also cleaned up on pinnipeds, with a big male Hooded Seal near Ny-Alesund being the highlight. Your bear shots are truly gripping!
Some nice shots of Humpies too - I have a feeling the western shelf-edge off of Spitsbergen is under-covered for marine mammals - we had at least 18 Blue Whales, along with plenty of Fin, Sei, Minke, Humpback, Sperm and a few Beluga west of Ny-Alesund. Still lots to be explored up there! Now I'm wondering whether to start my own trip report, yours has been a little inspiring!
