The Array for Real-time Geostrophic Oceanography (ARGO) is an international collaboration effort that has been established to collect temperature and salinity profiles data from the upper ocean to intermediate depths. The ocean data is collected using specially-built autonomous devices, drifting at sea. Since the year 2000, around 800 of these devices are installed each year.
 
While various models of these devices are in operation currently, the data collection proceeds in a similar fashion. After ten days of drifting at various depths, the devices pump fluid into an external bladder as a way to rise to surface. Within the 6 hours of ascent the devices record information on sea salinity and temperature. At the surface, the position of the devices is detected via satellites or GPS and the collected data is transmitted using satellite telecommunications. After the…

Scientists at NASA’s Jet Propulsion Laboratory have found that the ocean levels in Central and Eastern Pacific have increased between March and July 2015, which bears a resemblance to the conditions of the potent El Niño event of 1997-98. The research was carried out through altimetry measurements captured by the OSTM/Jason-2 satellite.

The scientists display a map where sea surface height is measured. Red colour indicates an increase in height due to higher temperatures compared to the average ones (thermal expansion), while blue shows a decrease in sea level because of temperatures lower than average (water contraction). White indicates normal sea level conditions.

They also compare the current situation with sea surface height in the Pacific during July 1997, which was captured by the former TOPEX/Poseidon mission. By analyzing the maps, they found out that the current situation seems even more intense than in 1997, when warming brought floods and landslides to…

The third Atlantic Tropical Storm of the season, Claudette, has been monitored by the RapidScat instrument that flies aboard the International Space Station.

As explained in NASA’s website: “RapidScat gathered surface wind data on the newborn Tropical Storm Claudette on July 13 from 6:31 to 9:36 UTC (2:31 a.m. to 5:36 a.m. EDT). RapidScat data showed that former System 92L had sustained winds near 24 meters per second (m/s) (53.6 mph/ 86.4 kph) in its eastern quadrant, and winds to 18 m/s (40.2 mph/64.8 kph) from the northern to southern quadrants. Winds in the western quadrant were 6 m/s (13.4 mph/21.6 kph) or less.”

The RapidScat instrument allows monitoring the movements of the newborn Claudette as well as the increase on the speed and potential weakening. This helps to predict the consequences it can cause and therefore mitigate the damages.

As a replacement for NASA’s QuickScat Earth satellite, the ISS-RapidScat is in charge of measuring Earth's ocean…

A new system of wildfire detection based on satellite data has recently been developed by the University of Berkeley in conjunction with Lawrence Berkeley National Laboratory, called Fire Urgency Estimation from Geosynchronous Orbit (FUEGO). It employs a satellite mounted with megapixel infrared cameras that monitors a patch of land in California. Then it sends the data to a geospatial information system on the ground that stores a large database of land use, rainfall, flammability and other factors related to fire emergency.

Astronomical satellites are exceedingly sensitive and could sense the outbreak of wildfires very early in their growth, when they are easier to contain and manage. Calculations show that with a reasonable half-meter aperture telescope and a contemporary multi-megapixel staring array sensor (as contrasted with the traditional scanning diode sensor), an extraordinary signal to noise ratio can be achieved, which is essential to quickly and reliably detect…

A new report by the international consulting firm Northern Sky Research (NSR) forecasts a boom for nano and microsatellites by 2024, which would lead to a significant diversification of the satellite industry. The report, entitled “Nano and Microsatellite Markets, 2nd Edition”, states that the market for sub-100 kg space artifacts has nearly doubled between 2013 and 2014, and operators have multiplied by three in just five years.

The developers of these nano and microsatellites are mainly universities, start-ups, small government agencies and military forces with low budget and limited time and expertise but who also participate in Earth Observation, science and risk awareness.

However, this sector also faces challenges, as the shortage of affordable launch vehicles, more efficient rideshares and limited orbital diversity. Therefore, the availability of venture capital and support from national agencies will be crucial for securing investment.
