Cold waters

Boundary called the “saturation horizon.” Above this boundary there are enough carbonates present in the water to support coral communities. In midlatitude waters and in waters closer to the poles, many so-called cold-water coral communities are found at depths that range from 40 to 1,000 metres (about 130 to 3,300 feet)—as opposed to their warm-water counterparts, the tropical coral reefs, which are rarely found below 100 metres (330 feet). Since about the year 1800, studies have shown, increased acidity has raised the saturation horizon about 50 to 200 metres (about 160 to 660 feet) in midlatitude and polar waters. This change is enough to threaten cold-water coral communities, and some scientists fear that additional communities will be placed at risk if the boundary approaches the surface of the ocean. A decline in cold-water marine calcifiers would result in a decline in reef building, and other marine organisms that depend on corals for their habitat and food would decline as well. Scientists also predict that, if ocean acidification were to increase worldwide, warm-water coral communities, which often supply food and tourism revenue to people who live near them, would suffer similar fates.In addition, scientists predict that the reduction of marine phytoplankton populations due to rising pH levels in the oceans will produce a positive feedback that intensifies global warming. Marine phytoplankton produce dimethyl sulfide (DMS), a gas that serves as the most significant source of sulfur in Earth’s atmosphere. Sulfur in Earth’s upper atmosphere reflects some of the incoming solar radiation back into space and thus keeps it from warming Earth’s surface. Models predict that DMS production will decrease by about 18 percent by 2100 from preindustrial levels, which will result in additional radiative forcing corresponding to an atmospheric temperature increase of 0.25 °C (0.45 °F).John P.

More technical fishing approaches like fly fishing or poling through skinny water to sight fish for sharks and redfish.Most of Hilton Head's shark species prefer the island's warmer waters from April through October. This is when you'll find the largest populations of inshore and coastal sharks that are the most popular targets on Hilton Head shark fishing charters.During the colder water season (approximately November through March) there are few sharks in our inshore waters, but some exceptions include occasional bonnethead sharks (a species of hammerhead) and some dogfish. Another notable cold water visitor is the Great White Shark, which is known to visit our coast during the winter. Shark Fishing during these months is much less consistent due to the lower populations, and most charters are going to be targeting other non-shark species such as Black Sea Bass, Sheepshead, Red Drum, and Spotted Sea Trout. Fishing activity in the winter tends to be better the further offshore you go, as water temps will usually be several degrees higher and likely to hold more fish.There are two things to considering when scheduling a shark fishing charter. First, make sure it's a comfortable time of day for your group and your schedule. Temperature is going to play a big part in this decision, especially when it's during extremes of weather like the peak summer heat, or on a particular cold day in the spring or fall. Your group composition (age, health, comfort) and how well you are prepared and equipped for shark fishing are important.Don't think you're limited to the evening hours for catching sharks. They are active throughout the day and whenever they have a chance to feed they usually will. Hilton Head shark fishing charters are often half day (~4 hour) charters scheduled in the morning or afternoon. If you

Enter its cool, clear waters, you’ll notice the lake’s remarkably high oxygen content. Lake Baikal contains 20% of the world’s unfrozen freshwater supply!Lake Baikal is also a great place for divers, who flock to its depths to explore the underwater treasures hidden beneath the surface. Even if you’re not a diver, you can still experience the lake’s underwater wonders. The lake is so clear that you can see objects up to 130 feet beneath the surface! The lake’s stunningly clear waters, untainted by mineral salts and filtered by tiny crayfish, are a marvel to behold throughout the year. Even in the cold Siberian winter, tourists flock to Lake Baikal to walk on the frozen lake’s glassy surface and peer into its depths.

Ft in NW swell and seas are 8-9 ft south of 20N between 40W-60W in mixed wind waves and NW swell. Elsewhere seas are 4-7 ft.For the forecast west of 55W, the stationary portion of the front will dissipate while the cold front shifts east of 55W late today. Rough seas following the front will subside to moderate through Sun. High pressure will build in the wake of the front over the western Atlantic along 30N. This pattern will support gentle breezes and slight to moderate seas north of 22N into early next week. The area of high pressure will shift eastward Mon enabling a weak cold front to move off the northeast Florida coast Mon night. Fresh to strong winds may pulse off the northern coast of Hispaniola late Sun through mid week. Looking ahead, another front may move into waters between northeast Florida and Bermuda late Wed.Posted 14 minutes ago by NHC Forecaster Landsea
