Unveiling the Mystery: Shifting Whale Shark Migration Patterns in the Arabian Sea and Ethical Encounters near Oman's Daymaniyat Islands
Unveiling the Mystery: Shifting Whale Shark Migration Patterns in the Arabian Sea and Ethical Encounters near Oman's Daymaniyat Islands
The vibrant coral reefs and diverse marine life of the Arabian Sea make it a haven for countless underwater wonders. Among these is the majestic whale shark, the largest fish species on Earth. These gentle giants have captivated scientists and tourists alike with their predictable seasonal movements. However, recent observations suggest a potential shift in their migration patterns, particularly near the pristine Daymaniyat Islands of Oman.
Established Whale Shark Migration Patterns in the Arabian Sea
Historically, whale sharks in the Arabian Sea followed a well-documented pattern documented in studies by Dr. Alistair Dove of the Marine Research Centre at the University of Salford, UK [1]. These seasonal movements are driven by the Southwest Monsoon. During the upwelling season (roughly May to September), plankton blooms fueled by nutrient-rich waters attract whale sharks to the area for feeding.
Shifting Patterns and New Discoveries in the Daymaniyat Islands
Recent observations by marine biologists at the Oman Aquarium and Marine Science Center near Oman's Daymaniyat Islands suggest a potential change in this established pattern [2]. Sightings of whale sharks outside the typical upwelling season raise intriguing questions: are whale sharks altering their migration routes due to environmental changes, or are we simply uncovering previously unknown aspects of their behavior?
Possible Causes for Shifting Whale Shark Migration
Several factors could be influencing this potential shift. Climate change and warming sea temperatures are known to impact ocean currents and plankton distribution, potentially altering the whalesharks' food sources. Additionally, increased fishing activities in traditional feeding grounds might be forcing these gentle giants to explore new areas.
Importance of Research and Conservation for Whale Sharks
Understanding these potential changes is crucial for the conservation of whale sharks. Continued research by institutions like the Oman Aquarium and Marine Science Center, along with international collaboration, will help us unravel the mysteries behind these shifting migration patterns.
Oman: A Leader in Whale Shark Research and Conservation
Oman has emerged as a leader in whale shark research and conservation efforts. The establishment of Marine Protected Areas (MPAs) like the Daymaniyat Islands provides safe havens for these magnificent creatures. Responsible tourism practices, such as regulated snorkeling trips with whale sharks, can generate revenue for conservation initiatives while fostering appreciation for these gentle giants.
The Daymaniyat Islands: A Paradise for Ethical Whale Shark Encounters
The Daymaniyat Islands, located off the coast of Muscat, Oman, offer a unique opportunity to witness these majestic creatures in their natural habitat. With its crystal-clear waters and thriving coral reefs, the islands are a designated MPA, ensuring a protected environment for whale sharks and other marine life.

Best time for scuba diving in Oman
Oman is a year-round diving destination. Depending on where you want to dive in Oman, you can go scuba diving at any time. Diving in Muscat is possible at any time of year. If you want to dive in Salalah and Mirbat, it’s best to avoid June to September as the Khareef, a seasonal monsoon, appears at that time. This Arabian landscape is turned into a lush green oasis but the diving stops for a few months. The conditions are too rough for diving boats to go out.
When it comes to diving in Muscat, it’s best between May and October. Conditions are at their calmest and water temperature ranges from 25°C to 30°C. Visibility can be above 10 meters at this time. During the summer, the outside air temperature may be too hot for some, reaching well over 40°C. The extreme heat can make visiting Oman during these months a challenge. Strong winds during summer can affect visibility. The water drops to 18°C in winter and rises to 30°C in summer.
In September and October, whale sharks can be spotted around Daymaniyat Islands and Al Fahal Island. During the winter months, December to February, water temperature is usually between 18°C and 25°C. The water clarity is usually the best during this time. As you can see, there are some trade-offs to be made when deciding on the best time of year to dive in Oman.
For those wanting warmer water, outside air temperature will also be very hot. During winter, water temperature drops but there are fewer divers during this time. One thing is for certain, no matter what time of year you decide to visit Oman, you won’t be disappointed.
Hands Signals to know when scuba diving
Ask any diver what they enjoy about scuba diving. Most will describe the absolute peace and tranquility of being at depth. Some will discuss the intense pleasure of not having to speak to anyone. So… how do you communicate with your buddies, dive master and other divers during a dive? Hand signals are the most common form of underwater communication. Let’s take a look at some of the most important ones to know.
OK / Are you okay?
The OK signal is the most important signal when it comes to diving. The ok is both a question and an answer. Join the thumb and index fingers while extending your third, fourth and fifth finger. The thumbs up signal indicates to go upwards or the end of a dive.
There's a problem
Have your palm flat and slowly move your hand from side to side, followed by where the problem is. Whether it's equalizing, your weight belt or something else, pointing out where the problem is will help your dive master, instructor or buddy to know what the issue is.
OK and problem at the surface
An OK at the surface is done by joining your hands above your head and can be used to signal the boat or lookout that you’re doing OK. This can also be done using one hand depending how far you are from the boat or shore. A problem at the surface is signaled by waving both hands and yelling ‘help.’
Thumbs up or down
Thumbs up can signal to ascend or the end of a dive. When you see this signal, you should also signal thumbs up to show that you’ve understood it’s time to ascend. A thumbs down is used to signal that the diver should descend.
Look at me or look over there
A scuba instructor will point at their eyes then at themselves to show students that they should look at what they’re about to demonstrate. A dive master during a fun dive may point at their eyes then in a direction to show that people should look in that direction.
Level off or stay at my level
Used to tell other divers to maintain their depth. It’s commonly used when you’ve reached your planned maximum depth or to tell divers to hold their depth for safety reasons. Extend your palm and move it slowly from side to side horizontally.
Buddy up
If you’re too far from your buddy, you may be asked to buddy up. This is done by using both index fingers and placing them close together.
Safety stop
A three minute safety stop at five meters is demonstrated by a flat open hand with your other hand below it indicating three. This means that divers should level off and start their safety stop.
Decompression
The deco signal can be done by either raising a pinky or raising a pinky and thumb. This signal is used in the event that a diver has passed their no-decompression limit and to communicate the need for an extra safety stop.
Low on air
Once you’ve reached 50 bar or go into the red on your gauge, you should signal to all other divers that you are low on air. This is done by placing a fist in front of your chest.
Out of air
In the unlikely event that you run out of air during a dive and other buddies are close by. You can signal you have run out of air by moving a flat hand across your throat which indicates your air supply has been cut off. Your buddy should then give you their alternate and you can start to ascend.
How much air do you have?
Your dive master and buddies may ask you how much air you have during a dive so you can adjust your dive depending on how much air the group has left. This is done by placing your index and middle finger into the palm of your other hand and tapping. To signal half a tank, form a time-out with your hands, 50 bar is done with a closed fist. Each additional 10 bar is indicated with the fingers on your other hand.
Stop/hold
You may be asked to stop or hold a position. To indicate this, hold a flat hand pointing forward or hold your forearm up and make a closed fist.
Come here
An open hand and moving your fingers towards yourself in a beckoning motion is used to signal to other divers to come here.
Now we've taken a look at some of the most popular underwater hand signals. What's your favourite one to use during a dive?
5 Tips for New Divers
Learning how to dive is one of the most exhilarating feelings in the world. Once you’ve completed your Open Water Course, what’s next? Let’s take a look at some of the best tips for new divers.
Practice, Practice, Practice
Have you ever heard of the statement: “practice makes perfect?” When it comes to diving, this is very much the case. The more time you spend in the water, the more time you have to develop your skills. Working on your buoyancy, kicking technique and air consumption becomes easier the more time you spend in the water. Practicing the skills, you learn during your course will help keep them fresh in your mind. Find a buddy or dive club and take some time during a dive or between dives to work on your skills. Try not to leave it too long between doing the course and getting yourself in the water.
Buy a Mask and Fins 
A properly fitted mask and a set of fins that do not give you blisters are the difference between a good dive and a dive you would rather forget. A mask that does not leak or fog will help you be able to see the wonderful marine life while diving. Comfortable fins will help you keep up with the rest of the group and not let you get tired. As you progress, you can start buying all the other types of dive equipment. If you’re considering buying a mask and fins, get in contact with us at Aura Divers, we’ll be happy to provide you with guidance and advice about different diving equipment and where to purchase it in Muscat, Oman.
Drink Water
Staying hydrated while diving is incredibly important. It can decrease your chances of getting decompression sickness. Drinking electrolytes is a fast and easy way to replenish after a dive. Be sure to drink water, before and after the dive, even at the end of the day. Keep drinking water!
Learn how to control your buoyancy
So, you’ve done your Open Water Course but still tend to swim with your arms or rise up and down? Having good buoyancy is not about constantly inflating and deflating your BCD. Mastering your breath will automatically help you with your buoyancy. Being properly weighted and reacting to changes in depth are important. Using the dump valves on your BCD will help keep you horizontal while letting air out of your BCD. Learn from other divers and your future dive guides. In addition, observe how they position themselves in the water and swim, find a role model and try to copy what they do.
Develop your Buddy Skills 
Becoming a good dive buddy takes time. Learning how and when to interact with your buddy is important. Staying close during the dive and communicating with your buddy is vital. Be aware of your surroundings and watch out for your dive buddy in case they do need your house. If your buddy needs assistance or you can see something that may turn into a problem, you have the ability to help them and reduce the risks. Check on their air consumption and make sure you’re diving within your limits. Understanding your buddy’s limits can help you adjust the dive plan.
Becoming a good diver takes time and practice. Actively trying to become a better diver is important. With more time in the water, things that were once daunting become much easier. Remember to keep learning and developing your skills as a diver. Consider taking further courses like the PADI Advanced Open Water course or a specialty like Peak Control Buoyancy or the Deep Diver course.

Refresh or ReActivate your Scuba Diving Skills with Aura Divers
Has it been a while since you’ve been diving? Want to get back in the water but don’t know where to start?
PADI offers two different courses to help you refresh your scuba diving knowledge and skills: the PADI ReActivate Course and the PADI Refresher Course. The PADI ReActivate Course is a course for certified divers that want to refresh all the diving skills they learn during the Open Water Course. The course consists of online theory, confined water session and an optional open water session. The Refresher Course can be done in a few hours and before open water dives. It consists of a quiz and practicing in-water skills.
To do a Refresher or ReActivate course, you need to have an entry level certification from any organization. Whether to do a PADI Refresher or ReActive Course depends on how long you’ve been out of the water and your certification level. It’s recommended to do a PADI Refresher if you’ve been out of the water for longer than a year. If it’s been longer than 2 years’, the PADI ReActivate Course is the way to go. If you haven’t been diving since your initial course, it may be better to consider the PADI ReActivate Course. Both of these courses are useful for people that are a bit apprehensive about scuba diving.
PADI ReActivate
The PADI ReActivate Course is part eLearning where you can watch videos on how to perform the necessary diving skills. It helps you relearn dive theory. If you have any questions, write them down and make sure to ask your dive instructor when you see them. You’ll go over the content from your initial course like: dive planning, equipment assembly and safe diving practices. With your instructor, you can do an in-water session in a pool or confined open water. During the in-water session, you’ll go over ALL the skills from your Open Water Course.
PADI Refresher
In comparison, A PADI Refresher Course is slightly different. It goes over basic diving practices, including alternative air source use, how to clear a mask, setting up and disassembling dive gear, and how to recover your regulator. At the start, complete a quiz which you’ll go over with your dive instructor which covers dive theory and safety practices. There is no eLearning as part of this course.
At Aura Divers, we offer both Refresher and ReActivate Courses. Give us a call to discuss which is the best for you!
