The aa index is a simple global geomagnetic activity index, with units of 1 nT (nanotesla), which is produced from the K indices from two approximately antipodal observatories. At present these are Hartland observatory in the UK and Canberra observatory in Australia. The main advantage in using aa indices for research purposes is that the time series spans further back (to 1868) than any of the other planetary indices time series.Also, up to date values are produced and made available weekly, giving nearer...

A layer represents aquifer media with direct of assignment of A index values for each aquifer delimitated.Higher values of “A” factor correspond to alluvial quaternary aquifers and Miocene sedimentary formations (sands and gravels). Smaller values represent areas with metamorphic and igneous rocks.

The aquifer media layer is created by direct assignment of aquifers to A index values from 1-10. The metamorphic and igneous rocks were given the lowest ‘A’-value of 3 and the karstified limestone is given the highest value of 10. The majority of the catchment can be grouped into bedded sedimentary rocks and given a value of 6.

New acquisitions of all forms of geological data received from external organisations are recorded in the accessions database and the digital or analogue data itself is then available to users. Data is in the form of reports, plans and digital information. This information comes from a wide variety of sources, including public bodies and agencies and commercial organisations. The data itself will be incorporated into existing corporate collections or may form a new collection in its own right. The rate of ...

The groundwater systems of northwest India and central Pakistan are amongst the most heavily exploited in the world. Groundwater has been monitored in the region for more than a century resulting in a unique long-term record of groundwater level change. The BGS has compiled groundwater level data from northwest India (Haryana and Punjab) and Pakistan (Punjab) between 1884 and 2020. The dataset, presented here, was compiled from various sources between 2018 and 2020. The excel file consists of two tabs both...
