Bay Water Characteristics
A shallow submarine ridge marks the mouth of Winter Quarters Bay. Water depths in the bay range from 13m along the ridge to a maximum depth of 33m at the bay's center.
The submarine ridge and Hut Point Peninusula temper the effect of McMurdo Sound ocean currents. Current meters indicate such minimal currents that the bay can be considered essentially stagnant. In addition the submarine ridge tends to provide a buffer against icebergs moving into the bay and damaging the ice pier and shoreline. Physical barriers created by such land forms have also concentrated toxic pollutants introduced into the bay from operations at McMurdo Station, according to a 1997 U.S. National Science Foundation sponsored study.
The combination of sun and sufficiently warm air temperatures a few days during midsummer can produce snowmelt on adjacent Ross Island. The subsequent runoff is largely diverted by ditches and culverts into McMurdo Sound, rather than the bay, according to the National Science Foundation report.

Famous quotes containing the words bay and/or water:
“Three miles long and two streets wide, the town curls around the bay ... a gaudy run with Mediterranean splashes of color, crowded steep-pitched roofs, fishing piers and fishing boats whose stench of mackerel and gasoline is as aphrodisiac to the sensuous nose as the clean bar-whisky smell of a nightclub where call girls congregate.”
—Norman Mailer (b. 1923)
“It is so manifestly incompatible with those precautions for our peace and safety, which all the great powers habitually observe and enforce in matters affecting them, that a shorter water way between our eastern and western seaboards should be dominated by any European government, that we may confidently expect that such a purpose will not be entertained by any friendly power.”
—Benjamin Harrison (1833–1901)
