Fukushima's "impacts on the ocean will exceed those of Chernobyl"

As quoted in the article by Elizabeth Grossman in the entry below:

“Given that the Fukushima nuclear power plant is on the ocean, and with leaks and runoff directly to the ocean, the impacts on the ocean will exceed those of Chernobyl, which was hundreds of miles from any sea,” said Ken Buesseler, senior scientist in marine chemistry at the Woods Hole Oceanographic Institution in Massachusetts. “My biggest concern is the lack of information. We still don’t know the whole range of radioactive compounds that have been released into the ocean, nor do we know their distribution. We have a few data points from the Japanese — all close to the coast — but to understand the full impact, including for fisheries, we need broader surveys and scientific study of the area.”

Given this need for more scientific data, why is the Obama administration EPA, NOAA, and FDA discontinuing emergency radiation monitoring set up after the Fukushima nuclear catastrophe began -- especially considering the radioactive releases into the ocean are continuing as we speak?!
