The salinity of the water is measured with a CTD instrument (Conductivity, Temperature, Depth). The conductivity is used to calculate the salinity in conjunction with the temperature and depth (pressure) measurements.Seawater has an average density of 1.027 gm/cm 3, but this varies with temperature and salinity over a range of about 1.020 to 1.029.he salinity of the water is measured with a CTD instrument (Conductivity, Temperature, Depth). The conductivity is used to calculate the salinity in conjunction with the temperature and depth (pressure) measurements.
The Multifocal Electroretinogram. What is the Electroretinogram (ERG)? The electroretinogram (ERG) is a recording of the bioelectric potential, the summed activity of the retinal cells located at the back of the eye, when stimulated by light. When bioelectrical changes occur within the retina, the change is propagated to the surface of the cornea.
