From the beautiful, but isolated salt flats of Bar al Hikman, sheltered from the seas by Masirah Island, Mark has reached the midway point of the expedition. After an amazing couple of days back in the kayak and 40 days since he started paddling, Mark has reached the halfway point of his journey along the coastline of Oman.

Tim, Marks land-based support, has headed inland to circumnavigate the salt flats leaving Mark alone for a few days. Always the avid birdwatcher, Mark saw a huge flamboyance of flamingos on the salt flats along with thousands of other birds and moved in closer for a look. But Flamingos wade in very shallow water and the falling tide caught Mark out. But always one for an adventure within an adventure, Mark took advantage of the water drying out around him and explored the mangroves.

As well as some of the wildlife he came across old wrecks, ruined shelters, a crashed aircraft and a haunting sight, hundreds of turtle shells. Eating turtles is forbidden in Oman today, but this was clearly a site of turtle hunting in years gone by.

After the tide came in Mark refloated his kayak and kept on paddling for a few hours into the darkness to find somewhere camp.

After 38 kms paddling today he is elated and well rested at the halfway point of the expedition.

The coastal waters Mark is paddling through are blooming into life. The upwelling cooler water is bringing with it nutrients from the deep, providing the fuel for the phytoplankton soup that plays such pivotal role in the food chain of the marine ecosystem.

This phytoplankton bloom has given Mark a wonderful sight, bioluminescence has been lighting up the water as every waves crashes onto the shore of his night time campsite. He is camping on the edge of the Sharqiya Sands. Formerly known as the Wahiba Sands, it is one of only 3 fog deserts in the world and an incredibly rare, isolated sand sea ecosystem, making it an ideal living laboratory.

In this podcast, join Mark in conversation with long-time friend of Oman, the inspirational Nigel Winser. In the mid-1980s, as deputy director of The Royal Geographical Society in London Nigel led The Wahiba Sands Project, a multiyear multidisciplinary study of this unique environment.

As Mark launches into the next stage of the Oman 3165 Expedition he drops into see marine ecologist Andy Willson in Muscat. Andy set up Future seas, an Oman based marine research and conservation company and has been a huge supporter of the expedition.

During the expedition pause, Andy has been servicing the hydrophone and setting up the analysis of the recordings Mark has been gathering each day.

In this fascinating conversation, Andy gives Mark a preview of the marine habitats he will be passing through and an insight into the oceanography that makes this section of the Omani coastline so special.
