Windward island shorelines are projected to accrete toward the island’s longitudinal ends and lagoon due to SLR, whereas leeward islands erode along lagoon shorelines and extend toward the island ends. ![]() Modeled atolls with comparably small diameters, narrow and deep reef flats with narrow islands displayed greater magnitudes of erosion and/or accretion, especially with SLR. Modeled morphologic parameters that significantly influenced alongshore transport were the atoll diameter, reef flat width, reef flat depth, and island width. The magnitude of the transport gradients increased with SLR: initial erosion or accretion patterns intensified. Incident wave transformations were simulated using a physics-based numerical model and alongshore erosion and accretion was calculated using empirical formulae. Schematic atoll models with varying morphologies were used to evaluate the relative control of individual morphological parameters on alongshore transport gradients. It is unclear, though, how potential atoll morphologic configurations influence shoreline erosion and/or accretion patterns, and how these relationships will respond to future sea-level rise (SLR). 2Pacific Coastal and Marine Science Center, US Geological Survey, Santa Cruz, CA, United StatesĪtoll islands’ alongshore sediment transport gradients depend on how island and reef morphology affect incident wave energy.1Institute of Marine Sciences, University of California, Santa Cruz, Santa Cruz, CA, United States.But if you are looking for something cheap and simple this is an OK trip.James B. If you are looking for an unforgettable snorkeling adventure I would suggest finding another excursion and of course that involve a higher excursion price. I would probably not take this trip in the future. On our way back we saw the houses of rich and famous, some pretty views from Atlantis and. We were in shallow water for an hour the staff brought food for the fishes and kids were able to see some cute fishes and some turtles. Staff was friendly and they will guide you along the reef, the snorkeling equipment is provided prior to departure and they have drinks for a fee. We have done snorkeling in beautiful places before and we were a little disappoitned when they took us to just one spot, nothing special or interesting but as I said you get what you paid for! ![]() Last minute excursion, cheap price ($41) and kind of blah. hey when you have two teens that's not a smart option! So away we go to Athol Island Snorkeling. I was in Bahamas last Friday as one of my NCL cruise's destination my eighth time visiting this port! It was raining and we were thinking about staying on the ship but. Small snacks and beverages were available for purchase.įor a quick and relatively cheap snorkel trip where you see several fish this was ok, but we would not go back. However, the motor was quite loud so that we were not able to hear most of it on the lower deck. Due to the amount of people in the water you had to watch out not to get hit by fins or hands.ĭuring the ride back the guide pointed out several villas that are owned by celebrities. We saw many fish at the reef and close to the boat as one of the staff members fed the fish. ![]() We were not allowed allowed to swim closer to the island due to the boat traffic. There were three other boats next to ours at the reef in front of Atholl Island, lots of people in the water. The trip to the reef took about 25 min, snorkel gear was in ok condition. After a 15 min walk to the spot where the boat would pick us up, we waited about 10 min for the boat to arrive. ![]() We were picked up at the pier next to the ship. Booked this excursion last minute on our cruise on the Norwegian Escape for $49 per person.
