DWARF SPINNER DOLPHINS

Hi again from a very hot a humid Croker Island

Nancy arrived back at Croker on Tuesday after three weeks in Darwin getting to know our grandson Noah.  She also spent some time with other family - sorry Jayse, Kristy and Dean but you have been 'bumped' by Noah. Haha. Our little dog, PK gave Nancy a very energetic and warm welcome at the Croker Island airport, racing out onto the aircraft parking apron to greet her - no airport security here!! 

After months of windy south east trade winds we have moved into the build up season which brings light winds but much warmer and more humid weather. 

On Thursday ranger Clayton and I (Bryan) did a boat patrol around the outer islands. 

As you will see in the first photo and the videos below the water was glassy smooth with great visibility. Ten kilometers out we came across a group of small dolphins - most were only about half grown. We stopped, switch the motor off and watched these amazing creatures swim playfully around the boat for 20 minutes. At the start the first video you can see the northern part of Croker Island's east facing coast in the background.

In the next video take careful notice of one of the smaller dolphins who has a white mark on it's tail. We believe this is bite from a shark.


In this video we actually caught site of a couple of sharks swimming below the dolphins. If you look very closely you should be able to see one shark. The substance floating on the surface of the water is coral spawning which happens naturally at this time of the year. 

We sent some photos and videos of the dolphins to a marine researcher at the Charles Darwin Uni (CDU) and they identified them as Dwarf Spinner dolphins, the smallest species in Australia. Not a lot is known about them. It looks like we will be assisting in some marine research work over the next few years with CDU. This will include manta rays, dolphins, false killer whales, dugong and turtles. 

The video below captured some great cloud reflections on the glassy water. 

Until the next blog post, take care and God bless.

Bryan and Nancy

Days like that day are definitely what 'keep the fires burning'. They make up for the hot days spraying weeds or the frustrating head office bureaucracy and ever increasing admin work. Cheers Bryan

A GRAND DAUGHTER - WELCOME AMELIA

Hi everyone,  Recently a beautiful granddaughter joined our family - welcome Amelia. We were able to meet her while visiting Darwin recently. Below are a few photos of Amelia with Granny and Pa. What a blessing she is! Noah is growing quickly. He does not have to be asked twice to go to the nearby playground. Noah and Amelia getting to know each other - beautiful!! Laura has recently been touring in Italy and Croatia. She had a ball and already has a few ideas for the next trip. She is coming to Darwin next weekend for a friend's wedding - we are all looking forward to catching up again. Nancy and I are flying into Darwin for the weekend. Noah - keeping us all laughing. Sadly, Kristy, Amelia and Laura were not in this happy photo. Jayson changed jobs earlier this year. This sees him working anywhere in and around Darwin and recently he has been back at Tindal RAAF Base near Katherine as part of the major upgrades happening there at the moment. Noah really looks forward to when uncl...

IFFV - Illegal Foreign Fishing Vessels

Hi  For a few months now we have been reporting Illegal Foreign Fishing Vessels (IFFVs) in our area. Some may have seen reports of Indigenous rangers in the Kimberley's, WA discovering IFFVs, often hiding in creeks and sometimes actually going ashore and camping. Concerningly, we have had the same issues around here. Apart from the illegal fishing aspect there is also a very real biosecurity risk. Indonesian has many diseases that we do not want in Australia - Foot and Mouth, Rabies etc. Last Monday we observed an IFFV in the area where we were conducting our marine research - but more about that later. Firstly, let's back up a little.  Last year we detected an IFFV near McClure Island - see the photo below. The crew were apprehended and the vessel destroyed. A couple of months ago we reported sightings of IFFVs around Croker Island and the adjacent mainland.  Around 3 weeks ago we discovered three IFFVs and one canoe hiding in the creek near where we subsequently setup o...

FAMILY, FIRES, HELICOPTERS and CARBON ABATEMENT

 Hi Last weekend we flew into Darwin for the weekend. Laura was flying up to Darwin for a friend's wedding. She had not met niece Amelia yet so I think the wedding was more of an excuse.  Dean, Kristy and their little family.  Aunty Laura meets Amelia. Granny and Pa with our grandchildren - a real blessing.  While in Darwin a friend from Inverness in Scotland was passing through Darwin. It was great catching up with Bev.  Trevor and Leonie were in town for the wedding. Leonie and Nancy met in the maternity ward in Gove hospital back in 1984. We have kept in touch even since.  Recently the Garngi rangers have been busy with our carbon abatement early dry season 'cool' burning. This involves both ground and aerial burning and if done well reduces the amount of carbon that ends up in the atmosphere. We receive some good income from this work.  For the aerial burning we use a Robinson R44 helicopter. The rear left door is removed and an incendiary machine ...
