or at least I never saw one - here's from the 4th - looks like they've made some improvements, including capping 1 of 3 leaks & offering better access to online weather conditions specific to the issue:
NOAA Web Update May 4, 2010
DEEPWATER HORIZON Incident
Situation - Tuesday 04 May - As the weather became better throughout the day, skimming, boom placement, aerial application of dispersants, imaging of the oil plume, in situ burning and observation overflights all took place in an effort to handle the oil leaking from the Deepwater Horizon Incident.
Remotely Operated Vehicles (ROVs) cut off a section at the end of the riser pipe, which used to lead from the well to the rig, and capped it with a valve. While this stopped one of the three leaks, oil continues to enter the Gulf of Mexico at a rate of approximately 5000 barrels (210,000 gallons) per day. Testing of a new technique that involves injecting dispersants at the oil's source - 5000' below the surface - will require further monitoring to tell whether the sub-sea dispersants are having an effect and further analysis to ensure effects in the water column are not worse than those from oil. If successful, the technique could reduce or prevent an oil plume from forming at the surface. Drilling of a relief or cut-off well got further, but will take several months to stop the flow. The first collection dome, a large cofferdam-like structure that collects oil at the sea floor and funnels it for collection at the surface, was deployed today. These containment chambers have never been tried this deep - 5000' - and will take about a week to be fully rigged and functional. Hundreds of thousands of feet of boom have been deployed to contain the spill, with hundreds of thousands more staged and ready to be deployed.
NOAA efforts have included: modeling the trajectory and extent of the oil, getting pre-impact samples surveys and baseline measurements, planning for open water and shoreline remediation, supporting the Unified Command as it analyzes new techniques for handling the spill and starting Natural Resource Damage Assessments (NRDA).
Decreasing wind and sea state should allow the full spectrum of surface operations until the weekend. NOAA's National Weather Service has created a special forecast for the incident area which you can access here: http://www.srh.noaa.gov/lix/
NOAA has 3 aircraft on-scene: a King Air specially equipped for photogrammetry and 2 Twin Otter aircraft one for marine mammal observations
The Coast Guard is using forecasts and graphics of oil movement prepared by NOAA's Emergency Response Division (ERD) and Marine Charting Division to keep mariners out of oil areas by depicting them on electronic charts.
NOAA restricted fishing in federal waters of the Gulf of Mexico directly adjacent to the area closures enacted by Louisiana. The closure, which will be in effect for at least 10 days, is to protect consumers and the seafood industry. NOAA fisheries representatives will be meeting with fishermen this week to assist them.
