- The
sample bottle number always matches the rosette
bottle number.
- The sample bottles are rinsed three times before the
final fill.
- If you have any doubt about the sample’s
integrity, redraw it.
- More than one person can draw a sample type but be
sure to keep the order straight, returning your bottle or tube to the
right spot.
- Notify your watchleader if you have to
“disappear” for more than a few minutes.
- Be available to help with CTD preps 20mins before the
station ETA. Station ETA is displayed on the navigation
monitor in the ship’s main lab. Occasionally, when
navigating around islands or coastline, the ETA displayed may be a
“waypoint”. These are turning points, not
the actual station arrival time. Check with the watchleader
if uncertain.
- If you will be unavailable to help because of other
work or illness, let the watchleader know. You are expected
to be available to help when you are on watch and the watchleader
should not have to go looking for you.
- Check with the watchleader before leaving for meals;
the CTD cast usually takes 45-50mins but shallow stations can be much
shorter so don’t leave until checking with him/her.
- Watches are 12 hours: 0000-1200 and
1200-0000. Be sure to get enough sleep especially if you are
on midnight (0000-1200) watch – it may take a few days to
adjust to this watch.
