Strange Metal Boxes on Oregon Beaches Debunked?

A story on a local, Oregon website - "Strange boxes spark UFO rumors," written by Terry Dillman - reports with obligatory dismissal on the sightings last week of the "mystery boxes" on Bray's Point and Stonefield beaches. Dillman insists the boxes were "wood-framed, fiberglass-covered dock floats," he dismisses the phenomena as internet rumor gone viral. Hong Kong reporter Yoichi Shimatsu believes the metal boxes are stepping transformers which floated from Japan. The strange heavy metal boxes float because the fluid inside is lighter than water. You can hear Shimatsu's take on the strange, metal boxes here: he suspects that the reason they were removed so quickly is that the boxes contained contaminants.

Clyde Lewis to investigate metal boxes on Oregon beaches

Strange metal boxes have turned up recently on Oregon beaches, following a flurry of UFO sightings. Clyde Lewis, Ground Zero Live Host, teams up with NW Ghost Recon set out, today, to Bray's Point and Stonefield beaches for a look. A report from Bray's Point, OR reveals, "They can’t be moved; even when yanked by a four-wheel drive truck pulling on heavy chains tied around these humming metal boxes that are still appearing as of Feb. 8 up and down West Coast beaches." In another report, this isn't first time similar metal boxes have turned up on beaches associated with UFO sightings, "the British government also photographed similar huge metal boxes on beaches in Sri Lanka in the late 1990’s and in early 2004 and 2005." Why are the boxes too heavy to move? What's inside the boxes that's humming?
