Maintenance and Update Frequency: annually Statement: Preliminary sediment trap data are indicative only and have not been quality controlled. Analysis of the samples is ongoing. A full dataset for this sediment trap deployment will be made available through the IMOS Ocean Portal when analysis is complete. The photograph file name format follows, using a typical example. s02_54_800_04.jpg signifies: 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, South 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 file names have additional information appended, 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. * a,b: Mostly for large samples when several sieves were used. Occasionally used with different lighting conditions. * bug: swimmer, often picked.

Credit Antarctic Climate and Ecosystems Cooperative Research Centre (ACE CRC) Credit Australian Antarctic Division (AAD) Sediment traps (IMOS platform code:SAZOTS) 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, but also including 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 ...
