A centimetre of water [1] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH 2 O (4°C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum water density of 1000 kg/m 3 is used, giving ...
Pentwater Lake is a water body adjacent to the village of Pentwater, Michigan. Its primary inlet is the Pentwater River; its outlet is a man-made channel flowing into Lake Michigan. Pentwater Lake has a surface area of 431 acres (174 ha), a maximum depth of 50 feet (15 m), and an average depth of 27 feet (8.2 m).
The name "Long Lake" is common among Michigan's 11,037 inland lakes which cover 1,305 square miles (3,380 km 2) of inland water. [5] This should not be confused with the other current and former Long lakes in Michigan , including the one in the vicinity of Long Lake Township , which is near Traverse City on the opposite side of the Lower ...
It can also be simply explained as the depth below which the ground is saturated. The water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0). It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity.
Depth data may be captured on camera from dive computers or depth gauges carried by the divers or mounted in view of the camera. The photos may be viewed on a map or via a geographic information system (GIS) for analysis. [3] This method can also be used for spatial surveys of small areas, particularly in places where a survey vessel cannot go.
The state averages from 30–40 inches (76–102 centimetres) of precipitation annually. Snow cover tends to be intermittent in the southern part of the state, but persistent in northern Lower Michigan and especially in the Upper Peninsula. Michigan USDA Plant Hardiness Zone Map. The entire state averages 30 days of thunderstorm activity per year.
Bathymeric charts showcase depth using a series of lines and points at equal intervals, called depth contours or isobaths (a type of contour line). A closed shape with increasingly smaller shapes inside of it can indicate an ocean trench or a seamount, or underwater mountain, depending on whether the depths increase or decrease going inward.
Long Lake is a large lake in the Lower Peninsula of the U.S. state of Michigan. Located about 6 miles (9.7 km) west of Traverse City, Long Lake is the largest lake in Grand Traverse County, and the 30th-largest inland lake in Michigan by surface area. [2] Its maximum depth of 70 feet (21 m) makes it the fifth-deepest lake in Grand Traverse County.
