in 2001, iceland began working on its submission to the commission on the limits of the continental shelf; it was scheduled to finish in 2007. the most important aspect of this work is to survey the entire ocean floor in the areas claimed outside the eez and, in iceland's case, a part of the area inside the eez as well. in all, 1.3 million square kilometres (500,000 sq mi) have been surveyed by icelandic marine research institutions for this purpose, an area 13 times larger than the land area of iceland. the commission does however not make proposals regarding areas that are claimed by two or more states unless they have already reached an agreement on its division. therefore, iceland's submission is expected to deal only with the area that just iceland has claimed and not the hatton-rockall area. iceland also hosted an informal meeting of all parties to the dispute in 2001. it was the first such meeting regarding the dispute where all four countries participated.
