Fears that ocean currents were spreading oil from the Gulf of Mexico spill flared on Tuesday after tar balls turned up in Florida, raising pressure on energy giant BP to capture more of the leaking crude Photograph: Daniel Beltra/Greenpeace/Reuters Photograph: Daniel Beltra/Greenpeace/guardian.co.uk On 17 May 2010, a large patch of oil was visible near the site of the accident, and a long ribbon of oil stretched far to the south-east. Oil slicks are not always visible in natural-colour satellite images. A thin sheen of oil on an already dark background may be impossible to detect. On this day, however, the slick was located in the sunglint part of the image, which makes the slick stand out Photograph: Terra/Modis/NASA Photograph: Terra/Modis/guardian.co.uk An aerial view of the oil Photograph: Daniel Beltra/Greenpeace/EPA Photograph: Daniel Beltra/Greenpeace/guardian.co.uk The mobile offshore drilling unit Development Driller II is prepared to drill a relief well at the Deepwater Horizon site Photograph: Patrick Kelley/USCG Photograph: Patrick Kelley/guardian.co.uk Gas from the damaged wellhead is burned by the drillship Discoverer Enterprise, 16 May 2010, in a process known as flaring.
