Above the 38 m depth, the water quantity of submarine ground-saline water is freshening.
Soil temperatures at 0.06 and 0.12 m depth, volumetric water contents and nitrate concentrations were determined at sowing, and harvest of each crop, and during sorghum's vegetative phase.

In the 2013 experiment, therefore, a packer was installed at 559 m depth, and water was injected into the 1800-m borehole through the screen at 1596 1671 m depth (Nishigami and Research Group of Water Injection Experiment at the Nojima Fault 2014).
Surface sediment (0 1 cm) samples were collected using an Ekman grab sampler with a lining of plastic inside from three random sites in shallow waters (0.5 1.5 m depth) of both water bodies and in deep water (6 8 m depth) of RAS.
The predatory aquatic beetle Agabus bipustulatus (Coleoptera: Dytiscidae) was collected with a kick net in shallow-water habitats (0.5 1.5 m depth) of both water bodies.
The optimum parameters for fishpond were 30 m length, 16 m breadth, 1.25 m depth, 1.0 m water depth, 75° lining inclination, and 8 air changes per hour for maximum temperature gain, maximum thermal efficiency and minimum thermal load leveling.
There was a significant distinction in both mean values and variability between the nearshore (< 30 m depth) and offshore waters.
For the whole period of culture 1.5 m depth and deep green water colour were maintained by occasional intake or discharge of water and periodic fertilization.
Phytoplankton and chlorophyll a were sampled at a 5 m depth with a LaMotte water sampler (Dynamic Aqua-Supply, Vancouver, British Columbia).
