Raw ADCP data for long-term observations of currents on the Prince Edward Island shelf at Mooring 1 (April 2014 - April 2015)

&
The raw data was collected using a bottom-mounted, upward-looking, 150 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) that was configured with a bin size of 8 m and a blanking distance of 3.52 m. The ADCP was deployed at location M1 (46.775°S; 37.900°E),in a depth of 166m, on the shelf between Marion Island and Prince Edward Island. The instrument measured hourly magnitude and direction throughout the water column between 07 April 2014 and 19...

A bottom-mounted, upward-looking, 150 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was deployed at location M2 (46.7115°S; 37.901°E), on the shelf between Marion Island and Prince Edward Island. A temperature sensor on the instrument measured hourly temperature readings between 06 May 2019 and 28 April 2020, at a depth of 256m. These hourly values were averaged to daily means. Daily values were only generated for days on which there were 75 % or more...

Physical exposition to landslides triggered by earthquakes

Helge Smebye
This dataset includes an estimate of the annual physical exposition of landslide triggered by earthquakes. It depends on the combination of trigger and susceptibility defined by six parameters: slope factor, lithological (or geological) conditions, soil moisture condition, vegetation cover, precipitation and seismic conditions. A population grid for the year 2010, provided by LandScanTM Global Population Database (Oak Ridge, TN: Oak Ridge National Laboratory) has also been used. Unit is expected average annual population (2010 as...

Suitable habitat for Bush Pig

The purpose is to provide a preliminary guideline on carrying capacities for game species suited to the Little Karoo. These are expressed as the estimated area (hectares) required per animal for the major habitat types present. It is a guideline for assisting landowners to utilize their veld at sustainable levels. There is no specific combination of game animals that will be suitable for introduction to all of the farms in the Little Karoo. The mix...

Renosterveld Conservation Status

This data layer shows ecosystem status for vegetation types occurring in the Cape Lowlands Renosterveld planning domain (see separate infosheet for planning domain). Ecosystem status indicates whether a particular vegetation type is `critically endangered`, `endangered`, `vulnerable` or `least threatened`. These categories are based on biodiversity targets (calculated for the National Spatial Biodiversity Assessment, NSBA, 2004) and on the extent (% area) of natural vegetation remaining for that particular vegetation type.

Monthly Means Of Daily Minimum Relative Humidity (%) August

, &
Daily minimum and maximum relative humidity is necessary as relative humidity, defined for practical purposes as the ratio of actual to saturated vapour pressure, expressed as a percentage generally varies considerably in the course of a day because, despite actual vapour pressure, ed, remaining relatively constant, saturated vapour pressure, ea, varies curvilinearly with temperature. The minimum RH of a day is thus experienced during the hottest part of the day when ea is high and...

Acacia mearnsii (timber) Growth areas and Yield estimation

&
A native of southeastern Australia, Acacia mearnsii is an evergreen tree growing to 15 m in height. A. mearnsii has proved to be the most drought resistant of the commercial hardwoods grown in South Africa (Herbert, 1993). Acacia mearnsii requires a MAP of 750 mm in colder areas and 850 mm where it is warmer (Smith, 1998). Ideally, mean annual temperature should be in the range 16 - 19 degree Celsius, but with A. mearnsii...
