Buoy 75

Initial Data Investigation:
Buoy Movement: Latitude and Longitude
Temperature and Salinity Profile for Day 14
Calculated Distance | Eyeballed Average speed: 3.0 km/day
Calculated Fresh Water Content for Day 14: 3.4 | Calculated Fresh Water Content: By day
Temperature and Salinity Profiles using Full Data
Calculated Density Profile using Full Data


Work in Progress(11/10):
Ice Velocity by Day | X vs. Y
First attempt at graphing stability frequency: Rough figure

Histogram of Ice Velocity X-direction | Y-Direction
  • About 73% of values are between -1.5 to 0.5 cm/s from the mean velocity for x-direction
  • Only about 14% of values deviate from the mean 1.5 or more cm/s (positive or negative) for x-direction
  • About 57% of values deviate with a negative value for the x-direction

  • About 72% of values deviate -1.5 to -0.5 cm/s from the mean for the y-direction
  • 80% of values deviate with a negative value. These values have a range of 2 cm/s for the y-direction
  • The 20% of values on the positive side have a range of 7 cm/s for the y-direction


    Discerning Patterns:
    Trial 1: Profile with northernmost points in blue and southernmost points in red
  • Temperature | Salinity
  • Latitude does not appear to be the strongest factor in observed pattern

    Trial 2: Temperature at 750m depth
  • Why investigate? Divider
  • By latitude | By day
  • The deepest waters appear to have temperatures of either 0.5 or 0.1 degrees

    Trial 3: Closer look at only temperatures greater than 1.1 degrees Celsius
  • Warmest Temperatures
  • The warmest waters have salinities ranging mostly between 34.7 and 35.0

    Investigating Speed of Sound (in meters per second) with varying ranges:
  • Range of 32 m/s
  • Range of 30 m/s
  • Range of 15 m/s
