Overview
McGarvey Shoal, located in the Bismarck Strait off the Antarctic Peninsula, is not a land-based cruise port but a significant submarine feature within the Southern Ocean. This underwater rise creates shallower waters that are incredibly rich in krill and other marine life, making it a vital feeding ground for a diverse array of Antarctic wildlife. For expedition cruises navigating this spectacular region, McGarvey Shoal represents a prime area for wildlife observation.
While ships do not dock or allow shore landings here, cruising through the vicinity of McGarvey Shoal offers an exceptional opportunity to witness the incredible biodiversity that thrives in these icy waters. The focus here is entirely on observation from the deck of your vessel or from Zodiacs, providing unparalleled views of whales, seals, and seabirds drawn to the abundant food source, all set against a backdrop of dramatic Antarctic landscapes.
McGarvey Shoal's rich feeding grounds make it an excellent location for whale watching. Keep a keen eye out from the ship's deck for various species of whales, including humpbacks, minke whales, and fin whales, as they breach, fluke, and feed in these nutrient-rich waters.
Tip: Spend time on the outer decks with binoculars and listen for announcements from your expedition team about sightings.
The waters around McGarvey Shoal are frequently dotted with ice floes that provide resting places for various seal species. Look for Weddell seals, crabeater seals, and potentially the formidable leopard seals hauled out on the ice, often visible from your vessel.
Tip: A telephoto lens for your camera is ideal for capturing detailed images of seals from a distance, respecting their space.
The abundance of food attracts a myriad of Antarctic seabirds to the area. Observe giant petrels, albatrosses, and various species of shearwaters and skuas soaring overhead and diving for food, showcasing their incredible aerial prowess.
Tip: Learn about the different seabird species from your onboard naturalists to enhance your birdwatching experience.
The journey through the Bismarck Strait and past McGarvey Shoal offers breathtaking scenic cruising. Marvel at the towering icebergs, the rugged, snow-capped mountains of the Antarctic Peninsula, and the dramatic interplay of ice, water, and sky.
Tip: Find a comfortable spot on the observation deck or bridge and simply absorb the majestic, ever-changing Antarctic panorama.
Maximize your understanding of this unique ecosystem by attending lectures and discussions with the onboard naturalists. They provide invaluable insights into the marine biology of the area, the behaviors of the wildlife you are observing, and the geological history of the Antarctic Peninsula.
Tip: Engage with the naturalists during deck observations; their expertise can help identify species and answer your questions.
McGarvey Shoal's location offers unparalleled photographic opportunities of Antarctic wildlife and landscapes. From majestic ice formations to intimate moments of marine animals, every view is a chance to capture the raw beauty of this remote continent.
