At Barataria Bay, La., just west of the mouth of the Mississippi River, large patches of oil the consistency of pancake batter in the still waters Monday. A dead sea turtle caked in brownish-red oil lay splayed out with dragonflies buzzing by.

The Barataria estuary, which has become one of the hardest-hit areas, was busy with shrimp boats skimming up oil and officials in boats and helicopters patrolling the islands and bays to assess the state of wildlife and the movement of oil.

On remote islands, oil visibly tainted pelicans, gulls, terns and herons.

President Barack Obama sought to reassure Americans on Monday by saying that "we will get through this crisis" but that it would take dedication.

"This will be contained," Obama said. "It may take some time, and it's going to take a whole lot of effort. There is going to be damage done to the Gulf Coast, and there is going to be economic damages that we've got to make sure BP is responsible for and compensates people for."

Among those people are Gulf Coast residents who make their living by fishing or operating tourist traps along the region's white-sand beaches. Allen said Monday that BP needs to make improvements on getting money to individuals and businesses harmed by the spill.

"It's not a core competency of BP so we're trying to get them some help," Allen said.

Wine, the BP spokesman, said the estimate of the proportion of gushing oil being collected is based on the government's contention that the containment cap is collecting 466,200 gallons of oil of the roughly 604,800 to 1,260,000 it believes is coming out daily.

Cutting the riser likely increased the flow of oil by 20 percent from the 504,000 to 1,050,000 gallons the government contends was coming out previously, Wine said.

Wine acknowledged the frustration people must have when they look at the undersea video feeds that show billows of oil still flowing into the sea.

"We want to capture every drop of oil that is still leaking," he said. "We want to protect the coastline and repair the coastline that has been damaged."

Officials say the current cap is collecting more than 460,000 gallons of oil per day. BP continues to drill relief wells in hopes of a permanent solution.
