| Title |
Strait of Gibraltar, Perspective with Landsat Image Overlay |
| Original Caption Released with Image |
Pasadena, CA, for NASA's Earth Science Enterprise, Washington, DC. View Size: 46 kilometers (28 miles) wide, 106 kilometers (66 miles) distance Location: 36 degrees North latitude, 5.5 degrees West longitude Orientation: Looking East, 15 degrees down from horizontal, 3X vertical exaggeration Image Data: Landsat Bands 1, 2+4, 3 as blue, green, red respectively Original Data Resolution: 30 meters (99 feet) Date Acquired: February 2000 (SRTM), July 6, 1987 (Landsat), This perspective view shows the Strait of Gibraltar, which is the entrance to the Mediterranean Sea from the Atlantic Ocean. Europe (Spain) is on the left. Africa (Morocco) is on the right. The Rock of Gibraltar, administered by Great Britain, is the peninsula in the back left. The Strait of Gibraltar is the only natural gap in the topographic barriers that separate the Mediterranean Sea from the world's oceans. The Sea is about 3700 kilometers (2300 miles) long and covers about 2.5 million square kilometers (one million square miles), while the Strait is only about 13 kilometers (8 miles) wide. Sediment samples from the bottom of the Mediterranean Sea that include evaporite minerals, soils, and fossil plants show that about five million years ago the Strait was topographically blocked and the Sea had evaporated into a deep basin far lower in elevation than the oceans. Consequent changes in the world's hydrologic cycle, including effects upon ocean salinity, likely led to more ice formation in polar regions and more reflection of sunlight back to space, resulting in a cooler global climate at that time. Today, topography plays a key role in our regional climate patterns. But through Earth history, topographic change, even perhaps over areas as small as 13 kilometers across, has also affected the global climate. This image was generated from a Landsat satellite image draped over an elevation model produced by the Shuttle Radar Topography Mission (SRTM). The view is eastward with a 3-times vertical exaggeration to enhance topographic expression. Natural colors of the scene (green vegetation, blue water, brown soil, white beaches) are enhanced by image processing, inclusion of some infrared reflectance (as green) to highlight the vegetation pattern, and inclusion of shading of the elevation model to further highlight the topographic features. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (99-feet) resolution of most Landsat images and will substantially help in analyses of the large Landsat image archive. Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, |

SeaWinds Global Coverage with Detail of Hurricane Floyd |
| Original Caption Released with Image |
The distribution of ocean surface winds over the Atlantic Ocean, based on September 1999 data from NASA's SeaWinds instrument on the QuikScat satellite, shows wind direction (white streamlines) at a resolution of 25 kilometers (15.5 miles), superimposed on the color image indicating wind speed. Over the ocean, the strong (seen in violet) trade winds blow steadily from the cooler subtropical oceans to warm waters just north of the equator. The air rises over these warm waters and sinks in the subtropics at the horse latitudes. Low wind speeds are indicated in blue. In the mid-latitudes, the high vorticity caused by the rotation of the Earth generates the spirals of weather systems. The North Atlantic is dominated by a high-pressure system, whose anti-cyclonic (clockwise) flow creates strong winds blowing parallel to the coast of Spain and Morocco. This creates strong ocean upwelling and cold temperature. Hurricane Floyd, with its high winds (yellow), is clearly visible west of the Bahamas. Tropical depression Gert is seen as it was forming in the tropical mid-Atlantic (as an anti-clockwise spiral), it later developed into a full-blown hurricane. Because the atmosphere is largely transparent to microwaves, SeaWinds is able to cover 93 percent of the global oceans, under both clear and cloudy conditions, in a single day, with the capability of a synoptic view of the ocean. The high resolution of the data also gives detailed description of small and intense weather systems, like Hurricane Floyd. The image in the insert is based on data specially produced at 12.5 kilometers (7.7 miles). In the insert, white arrows of wind vector are imposed on the color image of wind speed. The insert represents a 3-degree area occupied by Hurricane Floyd. After these data were acquired, Hurricane Floyd turned north. Its strength and proximity to the Atlantic coast of the U.S. caused the largest evacuation of citizens in U.S. history. Its landfall on September 16, 1999 resulted in severe flooding and devastation in the Carolinas. The high-resolution SeaWinds data provided an opportunity to monitor and study this hurricane. NASA's Earth Science Enterprise is a long-term research and technology program designed to examine Earth's land, oceans, atmosphere, ice and life as a total integrated system.

Both sides of the Atlantic Ocean are visible from Apollo 8 spacecraft |
| Description |
Both sides of the Atlantic Ocean are visible in this view from the Apollo 8 spacecraft. The large, most prominent, land mass is the bulge of west Africa. The portion of Africa near the equator is dark and cloudy, but the more northerly portions are clear, showing the prominent cape at Dakar and the Senegal River in Senegal, Cap Blanc, the Adrar Plateau in Mauritania, the wide expanse of desert in Algeria and Spanish Sahara, and at the far edge, the Atlas and Anti-Atlas Mountains in Morocco. Clouds cover the eastern coast of South America, southward from Surinam and Guyana to near the City of Salvador, Brazil. This view was taken after tranlunar insertion. |

Strait of Gibraltar |
| Description |
The Strait of Gibraltar as seen from the south (36.0N, 5.5W). This scene shows the actual Rock of Gibraltar under cloud cover but most of the Strait of Gibraltar, at the mouth of the Mediterranaen Sea and the Atlantic Ocean, can be seen in good detail. Despite the obliquity of the scene, much of the beauty of the Spanish and Moroccan countryside can still be appreciated. |

Morocco and border of spain as seen from STS-59 |
| Description |
The Atlantic Ocean, Straits of Gibraltar, and Alboran Sea (the westernmost portion of the Mediterranean Sea) separate Spain on the left from Morocco on the right. Algeciras Harbor is the prominent notch cut out of the eastern end of the north shore of the Strait, the Rock of Gibraltar is the tiny arrowhead that separates the notch from the Alboran Sea. The Sierra Nevada, farther away down the Spanish coast, lives up to its name in this April scene. The difference in elevation between the Sierra Morena and the Guadalquivir River valley is highlighted nicely by cumulus clouds. Tangier, Morocco can be seen as a light-toned spot on the southern shore of the Strait, near the entrance to the Atlantic Ocean. |

Strait of Gibraltar seen from STS-66 |
| Description |
Swift currents flow through the Strait of Gibraltar, producing complicated patterns in the surface waters. Some of those patterns are highlighted in the sunglint in this photograph. The Mediterranian Sea is on the upper right, the Atlantic Ocean in in the lower left. Few features can be seen on the Mediterranian side, but current shears (straight lines coming off Spain), several sets of internal waves (impinging on the Spanish continental shelf) and ship wakes can be seen on the Atlantic side, west of Cadiz. Both Tangier and Cadiz show up in the sunglint as well. |
