Does the change in ocean surface temperature between day and night affect CTD measurements in the same transect?
Can we use CTD Sections during the day and night time, or it's preferable to do CTD measures during only the day or only the night time, considering the change of temperature between day and night ?
Thanks in advance
Without being an expert, I believe it depends on what exactly you're studying. Probably the spatial scale and which kind of phenomena you're investigating is important to answer this question?
In figure 3 of this study Article Acoustics Reveals the Presence of a Macrozooplankton Bioclin...
is an example of physical parameters measured by CTD during night and day.
Maybe it's a little helpful.
Dear Naomi,
Thank you very much for your answer. The main phenomenon studied in north-west Africa is upwelling activity. So, I was wondering if we can confirm (conclude) with the CTD measurements whether upwelling is active or not, since we take CTDs during the day and night.
Cordially
