Subantarctic Zone photos of sediment trap samples

SAZ photos of sediment trap samples


Sediment traps are cones which intercept and store falling marine particles in collection cups. The particles consist of a range of material including phytoplankton, zooplankton, faecal pellets, and dust. Each trap collects a time series of samples. The sediment traps are from deep moorings in the Southern Ocean, typically at 47S, 54S, and 61S and at around 140 degrees East. Each mooring typically has 2-3 traps between 800m and 3800m below sea-level.

The samples are size fractionated into less than 1mm and greater than 1mm fractions using a 1mm sieve. Various chemical analyses and observations have been made on the less than 1mm fraction.


These are photos are of greater than 1mm fraction, mainly showing 'swimmers.'

Photos are mostly taken on the sieve, so the grid is 1mm for scale.

Sample identification is in the file name, and also in a label in the photo.

The file name format is:

Typical example s02_54_800_04.jpg

1) s02: s is for SAZ. Collection season number is first year of collection season. So s02 is from SAZ 2002-2003.

2) 54: Nominal latitude.

3) 800: Nominal depth, m.

4) 04: Cup number, typically 1-21 or 1-13, single digit numbers padded with a zero to help operating systems display files in order.

5) .jpg: All photos are in jpeg format


Some files have additional information at end, examples below:

* FP: faecal pellet

* begin and end: beginning and end of sieving process. Mostly to show faecal pellets at start that are rinsed through sieve.
