Mako Shark – Overview

The shortfin mako can grow to lengths of 3.9 meters (13 feet). There is still some uncertainty about its life-span, but it is suspected to reach ages of between 11-23 years.

As one of the fastest sharks in the ocean, this powerful shark can attain burst swimming speeds of up to 35 km/h (22 mph) and can leap clear of the water to heights of up to 6 meters (20 feet). These qualities have made this species a sought after sport fish in some parts of its range.

Mako Shark – Reproduction

Female shortfin makos usually become sexually mature at a length of 3 meters. Developing embryos feed on unfertilized eggs in the uterus during the gestation period of 15-18 months. The 4-18 surviving young are born live in the late winter and early spring at a length of about 70 cm, but have no placental connection during development (ovoviviparity). It is believed that females may rest for 18 months after birth before the next batch of eggs are fertilized.

Mako Shark – Habitat

Shortfin mako sharks live in tropical and temperate offshore waters. They are a pelagic species that occur from the surface down to depths of 150 meters (490 feet). This shark is seldom found in waters colder than 16 degrees Celsius.

Naval Air Station Keflavik

United States Naval Air Station Keflavik (NASKEF) is a former NATO facility [at Keflavík International Airport, Iceland] situated on the Reykjanes penninsula. It was closed on 8 September 2006.

The peninsula is marked by active volcanism under its surface, and large lava fields, allowing little vegetation. There are numerous hot springs and sulphur springs in the southern half of the peninsula, around the Kleifarvatn lake and the Krýsuvík geothermal area.

There is also a geothermal power station at Svartsengi. Near the power station is a swimming pool has been installed using the hot and mineralized water coming down from the power station; it is known as the “Blue Lagoon”.

Ocean Climage

Ocean currents and sea temperatures – Iceland, located at 63-67°N and 18-23°W, has considerably milder climate than its location just south of the Arctic Circle would imply. A branch of the Gulf Stream, the Irminger Current, flows along the southern and the western coast greatly moderating the climate (Figure 1). The cold East Greenland Current flows west of Iceland, but a branch of that current, the East Icelandic Current, approaches Iceland’s northeast- and east coasts. This is reflected in the coastal sea surface temperatures around Iceland. They are generally close to +2°C during the coldest months (January-March). Sea temperatures rise to over +10°C at the south- and west coasts of Iceland during the summer, slightly over +8°C at the north coast, but are coolest at the east coast where summer sea temperatures remain below +8°C. During years with heavy sea ice off northern Iceland, sea temperatures during summer can remain close to winter temperatures.
