  • The LeConte Inlet and Glacier were only a day's paddle from Petersburg so it was a good day out for me whenever I was living in the town. The glacier is the southernmost tide-water glacier in the Northern Hemisphere. I always enjoyed the challenge of trying to navigate my way through the congested ice floes, and then trying to photograph the seals without disturbing them, which most of the time I was able to do because of the stealth that a kayak provides. Being in a kayak also enabled me to get very close and low to icebergs so that I could take close-ups of the amazing icebergs sculpted into infinite shapes and forms, and luminescent with ethereal shades of blue and green. I always used the Indian method of anchoring with a rock tied to an anchor line resting on the bow, and then an additional longer bow line with the last half metre wrapped around the rock, so that when I pushed the kayak out and yanked on the long bow line the rock and anchor line were dislodged and fell into the water.

  • The harbor seal (Phoca vitulina), a widespread species in both the north Atlantic and Pacific oceans, is found in Alaska along the coast extending from Dixon Entrance north to Kuskokwim Bay and west throughout the Aleutian Islands. Harbor seals, and other phocid (true) seals, also are called “hair” seals, which helps distinguish true seals from fur seals. Harbor seals haul out of the water periodically to rest, give birth, and nurse their pups. In winter seals spend up to 80% of their time in the water. In spring and summer they spend more time hauled out during pupping and moult season. Reefs, sand and gravel beaches, sand and mud bars, and glacial, pan ice, and sea ice are commonly used for haul-out sites. The moulting lines on these seals are clearly visible.

  • Harbor seals show variable movement patterns depending on their sex and age class, with some exhibiting considerable localized travel but noseasonalpatterns,whileothersshowmoreextendedmovements,particularlyduringthewinter. Seasonaluseofglacialfjords,wheremanyfemalesaggregateto give birth on icebergs in the summer, is common. Satellite tagging studies have shown that pups may range up to 232 miles (374 km) from their birth site, although most movements are less than 62 miles (100km) away. Juvenile seals can make more extensive movements of up to 186-310 miles (300-500 km) away from their tagging location; however, most remain within 100km. Adult seals typically make shorter movements and on average are within 37 miles (60km) of their tagging site. More recent tagging of seals that occupy glacial fiords has revealed movements of seals from one glacial fiord to another as well as one extensive movement of a juvenile female seal from Glacier Bay in southeastern Alaska to Prince William Sound, an estimated straight-line distance of ~ 520 miles (830 km). As more seals are being satellite-tagged, much more information is becoming available about winter and summer movements.
