The size of the locks limits the size of the ships which can pass and so limits the size of the cargoes they can carry. The record tonnage for one vessel on the Seaway is 28,502 tons of iron ore while the record through the larger locks of the Great Lakes Waterway is 72,351 tons. Most new lake vessels, however, are constructed to the Seawaymax ...
A cargo ship discharging ballast water into the sea. Ballast water discharges by ships can have a negative impact on the marine environment. [1] Cruise ships, large tankers, and bulk cargo carriers use a huge amount of ballast water, which is often taken on in the coastal waters in one region after ships discharge wastewater or unload cargo, and discharged at the next port of call, wherever ...

Tregurtha got stuck in ice and cracked steel plating on the port side of her bow, causing ballast tank water to leak out. Framing beneath the ...
Clean-water advocates pointed their fingers at agriculture for contributing pollution to the annual algae bloom on Lake Okeechobee and other waterways. That blame was misdirected, Albritton said.
Florida’s BMAP system is failing to prevent high pollution levels in Lake Okeechobee. That contamination then flows into the St. Lucie River. Florida BMAPs could lessen Lake O pollution.
The state's efforts to monitor and enforce pollution control standards for Lake Okeechobee are inadequate. As a result, our water quality suffers. Florida must follow data, enforce rules to clean ...

Since Great Lakes waves do not achieve the great length or period of ocean waves, particularly compared to the waves' height, ships are in less danger of being suspended between two waves and breaking, so the ratio between the ship's length, beam and its depth can be larger than that of an ocean-going ship. The lake vessels generally have a 10: ...
