A&O SCI 200A · Lec 1

Introduction to Atmospheric and Oceanic Fluid

Fall 2026Mitchell, J.L.4 units

dibs reads this section's seats hourly, like everything else, but it does not send alerts for graduate courses yet.

Seats, time, final and grades

Seats

Waitlist, 0 of 5 places taken.

22 of 25 enrolled, lecture and all discussions summed.

Lecture itself reads open. Subtract those two and the lecture has 3 places in it. No discussion under it is open, and you enroll in a discussion, so those places are not seats you can take.

Meets

MW 1:30pm-2:45pm

Lecture only. You also attend a discussion, listed below.

Final

None on the page dibs read

No exam time on the page dibs read. That is not the registrar saying there is no final.

Put this class on a board

A board is one quarter you are drafting, so it needs an account to live in. Signing in brings you straight back to this page, with this class still in front of you.

Before you can enroll

Registrar's Restrictions cell, read 4 days ago: "Graduate Students".

Restrictions read 4 days ago. dibs re-reads these slowly because they rarely change, and it does not sweep graduate courses at all, so this one has no faster cadence to move to. Check the registrar.

Discussions

You enroll in the discussion, not the lecture, so the seat figure above is the sum across all of them and can read open while every discussion you could actually join is full.

1 discussion, none open.

No discussion is open. 1 discussion has a waitlist with room. A place on one is not a seat: it is a queue the department may or may not clear.

What students say

dibs measures outcomes: grades, seats, how fast it fills. For what the class is actually like to sit in, BruinWalk has the reviews.

dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.

Will it still be here

Not a question any more: see the notice at the top of this page.

dibs read 168 of the 541 hours its hourly record covers, 31%, and did not look in 373. dibs had no hourly record before 9 Sep, which is the other 556 of 1097 plotted.22 of 25 enrolled at the newest reading, 77 minutes ago, and no seats left in its discussions. Seats from 17 Aug 15:07 to 2 Oct 07:43, 18 to 22. dibs read 168 of the 541 hours its hourly record here covers, 31%. An hour marked as read confirms a check, not continuous monitoring. That check recorded no change; changes between checks may be missed. For 373 hours dibs was keeping a record and did not reach this section. Nothing before 9 September at 19:00, where this section's record starts, has a read either way, which is 556 hours of this window. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.

A dot is a reading where something moved: the seat count, the status, or the waitlist. Flat between dots joins recorded counts; changes between reads may be missed. The line starts when dibs first saw this section rather than reaching back before it existed. The last one is the last time dibs read this section, moved or not: 77 minutes ago.

How readings and alerts work

A reading and an hourly record are different things, and most charts here hold more of the second missing than present. dibs has taken readings of a section since long before it began keeping an hour-by-hour log of when it looked, so the empty stretches are dibs saying it was not keeping that log yet, not that it looked and found nothing. That is the age of the record and not a fault.

Seat counts show the last successful read, not live availability. Refreshes can be delayed by request limits or upstream interruptions. Watched sections receive priority, but an hourly update for every section is not guaranteed.

The registrar can change a seat count between our checks. Alerts depend on dibs detecting an opening and completing delivery; a quiet watch does not prove that no seat opened. Check the registrar before enrolling.
