Rising ocean surface temperatures caused by climate change could make fish accumulate more mercury, increasing the health risk to people who eat seafood, Dartmouth researchers and their colleagues report in a study in the journal PLOS ONE.
Until now, little has been known about how global warming may affect mercury bioaccumulation in marine life, and no previous study has demonstrated the effects using fish in both laboratory and field experiments. Mercury released into the air through industrial pollution can accumulate in streams and oceans and is turned into methylmercury in the water.
The researchers studied killifish under varying temperatures in the lab and in salt marsh pools in Maine. Fish in the marshes ate insects, worms and other natural food sources, while the lab fish were fed mercury-enriched food. Results showed the fish in warmer waters ate more but grew less and had higher methylmercury levels in their tissues, suggesting increases in their metabolic rate caused the increased uptake of the toxic metal.
Snorkeling is a sweet alternative with RAID
Swim gear, a towel, a mask and snorkel: what could be simpler? And there’s a lot to be seen from the surface, so that sometimes, breaking out the scuba gear isn’t necessary.
Did you know that RAID now has a swimmer-friendly snorkelling program? Perfect for hassle-free exploring for any diver, and a great alternative for anyone in the family who isn’t crazy about scuba.
This program has its official launch in late September 2023. To check out more about the program and to sign up with your local RAID dive centre, why not take a look at the official course page on the RAID website here.
Join Murex Resorts in North Sulawesi and embark on a Passport to Paradise!
Are you planning your next tropical diving holiday? With literally the world at your feet and so many different types of diving to choose from it can be tough deciding where to go…
The Indonesian province of North Sulawesi lies in the heart of a marine rich region and offers incredible wall diving in the Bunaken Marine Park: wreck, critters and reef combinations in Manado Bay; colorful coral reefs surrounding Bangka island; and the world’s best muck diving in the Lembeh Strait. So how do you begin to choose which region to allocate your holiday time to?
Whilst many divers have heard of these world class diving destinations, many may not realize the close proximity within which they are located. Taking a scuba diving holiday in North Sulawesi does not mean that you have to choose between locations – you can see all that is on offer and explore the areas which appeal to you – IN ONE TRIP!!!
Bunaken Marine Park was one of the ﬁrst Marine Protected Areas in Indonesia – and it shows! The dive sites around this small island are characterized by staggering coral walls which are teeming with life. The resident population of green sea turtles has grown from strength to strength and at some dive sites you’ll lose count of the number of turtles you see in a single dive.
Manado Bay is home to wide ranging marine life and diverse dive sites. Manado Bay is becoming increasingly recognized for its black sand, muck diving sites, which are home to a plethora of unusual critters from numerous cephalopod species through to seahorses, nudibranch and crustaceans. The Molas wreck is an exciting wreck dive and also offers a myriad of ﬁsh and critters. To the South of Manado Bay lays Poopoh – a record breaking site where 385 different species of ﬁsh were recorded in just one morning.
Bangka Island is as beautiful underwater as it is on land. This white sand, paradise island is surrounded by kaleidoscopic, soft coral reefs. Schooling snappers, passing reef sharks, occasional dugongs and an array of reef ﬁsh and critters have all made Bangka Island their home. Bangka offers phenomenal diving coupled with the chance to completely get off the grid on this stunning, remote tropical island.
The Lembeh Strait is home to the highest concentration of rare and unusual marine life on Earth. Exploring Lembeh’s world famous muck diving sites is akin to opening a treasure chest of critters. Even the most seasoned of divers can’t help but be impressed by the species found here: eight different species of frogﬁsh, ﬂamboyant cuttleﬁsh, wunderpus, mimic octopus, blue ring octopus, bobtail squids, harlequin shrimps, tiger shrimps, three species of pygmy seahorses, countless species of nudibranch, bobbit worms, Ambon scorpionﬁsh and rhinopias – just to name but a few!
The idea of moving from resort to resort can seem arduous and result in wasted diving days – but in North Sulawesi this does not need to be the case! Stay with us at Murex Manado (for diving Bunaken and Manado), and smoothly transition to Murex Bangka and then on to Lembeh Resort too. You can choose the number of nights you wish to stay in each location and transfers between resorts are by boat and include two dives along the way! No wasted diving days, no logistical planning, no drying and packing gear and your dive guide will stay with you from start to ﬁnish. Dive your way, hassle free, from one place to the next. Two resort combinations are also available.
For those of you who want to experience the full diversity of Indonesia, choose from up to 150 dive sites and maximize your diving opportunities – a Passport to Paradise is the dive trip of a lifetime.
