In this paper describes an oceanographic measuring station as a part of automated system for oceanographic measurement with remote control and data visualization. Oceanographic measuring station consists of operator's computer and a number of different measuring devices that produce data continuously. Each device has its own software interface that allows user interaction with the data. Such interface suffice when operator work with only few measuring devices and when the type (manufacturer) of a measuring device is not frequently changing, but it becomes cumbersome as more and more various devices became available for oceanographic data acquisition. In our setup the operator's computer is replaced by embedded computer dedicated to serve as a middle layer between sensor and database server with whom the operator communicates. The embedded Linux box run a set of daemons which acquire and archive data and transfer it to database, and a daemon that supervise the device and the entire process. A part of the acquired data is publicly available through visualization on Institute's website (www.izor.hr). The dynamic visualization of the data is done in javascript.
