King Tide Observations

The Highest tide here was on Friday 14th December at 09:42am at Merimbula Bay and Twofold Bay. It was 1.9m. The Tide peaked at Merimbula Bridge at 10:45am. Flow under the Bridge to Top Lake upstream continued until 11:31am (2 hours later than the peak of the tide out in the Bay). Conditions were calm. The water was slack for only a minute, then started to flow back out downstream towards the Bar. The level at the bridge had dropped between 10 – 20cm by the turn of the flow under the bridge.

Does anyone have any pictures of the top of the tide? If so please share them with us.

Pterotrachea coronata

Not a Carinaria – expert review – Petroacheid – possible world record!

This is our original post: Whilst at Shelly Beach Bermagui last Sunday(August 26 2012), Michael found the largest Carinaria yet. It was around 35cm long from feeding tube to tailtip. Although it had lost its shell, we could clearly see its feeding “trunk”, what looked like elementary “eyes” and its gut. It had fins underneath its body and a tail with tiny rows of markings. Here are the photographs Michael took later. We are still trying to find out more about these strange creatures. Please do keep a look out and report any sightings. Yesterday we received the post below from an expert, Roger Seapy. We had been finding Carinaria, as we have photos of their shells, but this obviously was another species altogether. Wow!

Witness the King Tides project – this week-end

Hi all
If you intend to Witness the King Tide the highest tide is predicted for Friday 14th at about 9.30 am. (The actual height will depend on the weather – higher if there is low pressure and strong onshore winds, lower if there is a high pressure system). If you can’t do Friday try Saturday at 10.26am.
On the open coast this will be the right time but delays occur in inlets and bays. For example, according to the tide chart, there is a delay for high tides of 54 minutes at the Narooma Bridge (fishers say 30 minutes), 45 minutes at Bermagui Bridge and Moruya, and 15 minutes at Clyde River Bridge.
Register to participate at www.witnesskingtides.org so you get photos of places that might be missed. Below are some tips from the website

Work out when to go?
The best time to take photos is at the peak of the tide when the water level is at its highest. This time varies both along the coast and within the estuaries away from the coast.

What shots to take?
Capture photos of local coastal areas that are subject to flooding or erosion. Take images where the impact of the tide can be gauged against familiar landmarks like buildings, jetties, bridges, roads, sea walls, shorelines, beach infrastructure or estuary shorelines.

If you can, take contrasting ‘before and after’ shots which help to show the average water level in the same location.

Be safe
Use good judgement when you are taking your photos. Stay away from dangerous situations particularly in stormy conditions and avoid taking risks.

Make a day of it
Take your family and friends with you and participate together. Why not enjoy the event together and witness the future. If you are keen to coordinate a group of people, get in touch and we can help you. Check out these Tide Tracking activity

Pied Oystercatcher

Pied Oyster Catcher…..seen again

This Pied Oystercatcher with the yellow flag marked JE on its leg was first banded 14 years ago at Corner Inlet in Victoria.

Since then various people have sighted it at Aragannu, Spencer Park[Merimbula ] ,Wallagoot Lake ,Tura beach , back at

Corner Inlet & again at Tura. So far its cumulative distance is 4335 km.

Let us know if you see this POC again.I have seen another 4 different flagged birds at Mogareka and will post an update when I know their details .

Mogareeka shorebird nesting site visit

Dr Peter Fullagar and Mike Crowley will be happy if you would like to join them to observe the Shorebird nesting site at Mogareeka on Saturday 15th December.

This is the most important nesting site in NSW for Little and Fairy Terns – 150 birds have been recorded recently. There are also Pied Oystercatchers, Red Capped Plovers and lots more.

Saturday may be interesting because it is a King Tide of around 2m predicted.

Meet at the car park at 10:00am
