The WARM buoy project (lead PI Victoria Hill, ODU) is designed to measure near-surface temperature and bio-optics in the Arctic Ocean. These buoys have a string of thermistors, similar to UpTempO buoys, as well as a suite of other optical and bio-optical sensors.

SUMMARY
The plot below shows the path of WARM 2015 #W-4 colored by month. The flag marks the buoy's last known location. Black contours show two isobaths: 28 m ("short buoy" max depth: e.g., 2011 APLIS buoy) and 60 m ("standard buoy"
max depth).
Please note that the quantities plotted below are not included in the data available on this site.

OCEAN PRESSURE AND SEA LEVEL PRESSURE
This plot shows the ocean pressure(s) from the barometers placed at nominal depths (left axis), and sea level pressure in red (right axis).WARM BUOY PARAMETERS
The Warming and Irradiance Measurements (WARM) buoy is designed to collect coincident observations of temperature and light intensity. The buoy string has sensors collecting visible light measurements within the ice at 0.5 and 1.0 m from the ice surface and within the water column at varying depths from the ice surface. Typically a Wetlabs Ecotriplet measures chlorophyll and dissolved organic material fluorescence at 5m depth. Thermistors are also located at various depths. The buoy is deployed in early spring (March/April) by drilling a hole through the sea ice (~2 m thick) and feeding the tether through the ice. The surface float is anchored to the sea ice to prevent the buoy from slipping. In the summer the ice melts and the buoy is able to float in open water until the fall when it is frozen back into the ice.

VELOCITY TIME SERIES
One to three hourly velocity is on the left axis.Distance between the buoy's start point and end point each day is shown in red on the right axis.Note that the total displacement of the buoy each day (red) is generally less than what one would calculate from the hourly velocities.
