ASL Mini Logger

The ASL Mini Logger gathers oceanographic sensor data and can be customized to suit your needs.  

The data can be stored locally on the logger or transmitted to shore in real-time. A shore station can then relay the data using various modem technologies to the cloud for access from the Internet. The shore station is usually configured to provide power to the logger. ASL supplies several options for shore stations including powering, modem antennas and other shore station infrastructure.
