PPT, or parts per thousand, is a measurement used to express the concentration of dissolved substances in water, including freshwater. In freshwater contexts, PPT typically refers to the salinity or the amount of salt content present in the water, with freshwater usually defined as having a salinity of less than 0.5 PPT. This low concentration of dissolved salts differentiates freshwater from saline water bodies like oceans. Thus, freshwater PPT is a key indicator of water quality and ecosystem health.
Water Ecosystems don't have PPT (precipitation).
Salinity can be categorized into several types, including: Seawater Salinity: The average salinity of ocean water, typically around 35 parts per thousand (ppt). Brackish Water Salinity: A mix of freshwater and seawater, with salinity levels between 1 and 30 ppt, commonly found in estuaries. Hypersaline Salinity: Extremely high salinity levels exceeding 40 ppt, often found in evaporation ponds or certain salt lakes. Freshwater Salinity: Water with very low salinity, usually less than 0.5 ppt, typical of rivers and lakes.

The salinity of the Persian Gulf is around 35 parts per thousand (ppt), which is slightly higher than the average ocean salinity of 33-35 ppt. This high salinity is due to the combination of high evaporation rates and limited freshwater input from rivers.
Salinity is the saltiness or dissolved salt content of a body of water. The average ocean salinity is 35 ppt. This number varies between about 32 and 37 ppt. Rainfall, evaporation, river runoff, and ice formation cause the variations. For example, the Black Sea is so diluted by river runoff, its average salinity is only 16 ppt. Freshwater salinity is usually less than 0.5 ppt. Water between 0.5 ppt and 17 ppt is called brackish. Estuaries, where fresh river water meets salty ocean water, are examples of brackish waters. Saline waters from inland seas can have a composition that differs from that of the ocean.
Freshwater on Earth is primarily stored in glaciers and ice caps, which hold about 68.7% of the total freshwater. Following that, approximately 30.1% is found underground in aquifers, while only about 1.2% of freshwater is available in lakes, rivers, and the atmosphere. Overall, freshwater constitutes about 2.5% of the Earth's total water supply.
The seawater salinity level around Greece typically ranges between 36 to 39 parts per thousand (ppt), which is slightly higher than the global average of about 35 ppt. This elevated salinity is influenced by factors such as evaporation, limited freshwater input, and the Mediterranean Sea's unique hydrography. Variations in salinity can occur due to seasonal changes, freshwater runoff, and local climatic conditions.
ppt = parts per thousand per cent = part per hundred so 10 ppt = 1 % and then 35 ppt = 3.5%
Earth's accessible surface freshwater is primarily located in lakes, rivers, and reservoirs, with approximately 87% found in lakes. Groundwater accounts for a significant portion as well, but only about 0.3% of the Earth's total freshwater is surface freshwater. Overall, surface freshwater constitutes about 0.3% of the total freshwater resources available on Earth. This limited availability highlights the importance of conserving and managing these vital water sources.
