Day 1 – Truck arrived. It was unloaded and the boats are now in the water. We have the instruments set-up and ready to go for tomorrow.
Day 2 – We got the instruments in today. Thermocline was felt with much warmer water on the bottom. Waves are picking up. We did a walking survey within the surf zone and dry beach.
Inshore sensors are in a rip channel. Below are the sensors listed from offshore to onshore (Note there is an offshore bar hence the rise and decline in depth):
- 10m depth – ADCP 1Hzsampling, CTD at the bottom 0.5Hz sampling, thermistor string 8 nodes 8s sampling
- 5m depth – pressure and temperature sensor on the bottom 1Hz sampling
- 4m depth – ADCP 1Hz sampling, CTD at the bottom 0.5Hz sampling
- 6m depth – pressure and temperature sensor on the bottom 1Hz sampling, thermistor string 8 nodes 8s sampling
- 3m depth – ADCP 1Hz sampling, CTD at the bottom 0.5Hz sampling
- 2m depth – ADCP 1Hz sampling, CTD at the bottom 0.5Hz sampling
Day 3 – Near shore drifter deployment – We deployed 53 drifters in an alongshore array and cross-shore array at the experimental site. Every drifter ended up on the beach.
Day 4 – East Pass Ebb Drifter Deployment – We deployed 13 drifters every hour from 6am-9am. 52 drifters in total. We retrieved 2 drifters in the end. They are still going! Will they end up on the beach?
