featureType can have only those values which are shown in Table 9.1. Each value means that the data has a particular geometry, as shown in the table. Your data > float seatemp(time, depth, lat, lon) does not have one of those geometries. In words, it isn't apparently a set of timeseries, or a set of profiles, or any other of the possibilities. It's a variable with four independent spatiotemporal axes. This is the "usual" type of gridded domain which CF has always supported. In the discrete sampling geometries the spatiotemporal axes aren't all independent. Therefore I don't think you can use the featureType attribute with your data as it stands. If the data was > float seatemp(station, time) it would look like a collection of timeseries, so you could give it featureType="timeseries".
