What is command "?POOL;"?
POLL of course, sorry.
"POLL" returns the current state on that "DEVICE". Since your depth is only reported intermittently, most of the time POLL will not return the depth.
"current state" must be the last existent value from timestamp, not current. Else this behaviour makes POLL mode pointless. https://gpsd.gitlab.io/gpsd/gpsd_json.html#_poll speaks about caching values -- it's reasonable.
