Seafloor Dissolved Oxygen (ml/l)

<div><span style='line-height: 1.38462;'>The concentration of dissolved gases in water is of prime importance in considering the quality of water. Sufficient amounts of dissolved oxygen are required for marine-life survival. Dissolved oxygen levels are influenced by temperature and salinity.The ability for oxygen to dissolve in water (solubility) decreases as temperature and salinity increase. Poorly oxygenated areas, or those with a dissolved oxygen level below 1, are considered </span><a href='https://oceanservice.noaa.gov/facts/deadzone.html' rel='nofollow ugc' target='_blank'>dead zones or hypoxic zones</a><span style='line-height: 1.38462;'>. Dissolved oxygen is carried to the deep-sea floor by the descending surface waters.</span><br /></div><div><br /></div><div><div style='margin: 0px; padding: 0px; background-color: rgb(255, 255, 255);'><b>Phenomenon Mapped:</b><span style='color: rgb(77, 77, 77); font-family: '> </span><span style='background-color: transparent; font-size: 14px; line-height: 17.6224px;'><font color='#4d4d4d' face='Lucida Grande, Lucida Sans Unicode, Arial, Helvetica, sans-serif'>Seafloor dissolved oxygen</font></span><br /></div><div style='margin: 0px; padding: 0px; color: rgb(77, 77, 77); font-family: '><div style='margin: 0px; padding: 0px;'><b>Units:</b> Milliliters per liter (ml/l) </div><div style='margin: 0px; padding: 0px;'><b>Cell Size:</b> <span style='font-family: '>30 arc seconds, approximately 1 km</span></div><div style='margin: 0px; padding: 0px;'><b>Source Type: </b>Discrete</div><div style='margin: 0px; padding: 0px;'><b>Pixel Type: </b>Unsigned integer</div><div style='margin: 0px; padding: 0px;'><b>Spatial Reference: </b>GCS_<span style='line-height: 16.3636px;'>WGS_1984</span></div><div style='margin: 0px; padding: 0px;'><span style='line-height: 16.3636px;'><b>Mosaic Projection: </b>Web Mercator Auxiliary Sphere</span></div><div style='margin: 0px; padding: 0px;'><span style='line-height: 16.3636px;'><b>Extent:</b> Global oceans</span></div><div style='margin: 0px; padding: 0px;'><b>Source:</b> <a href='https://marine-conservation.org/' rel='nofollow ugc' style='line-height: 1.38462;' target='_blank'>Marine Conservation Institute (MCI)</a></div></div><div style='margin: 0px; padding: 0px;'><div style='margin: 0px; padding: 0px;'><div style='margin: 0px; padding: 0px;'><b>Citation: </b>Garcia HE, Locarnini RA, Boyer TP, Antonov JI (2006) World Ocean Atlas 2005, Volume 3: Dissolved Oxygen, Apparent Oxygen Utilization, and Oxygen Saturation.
