Introduction ^^

The year 2000 marked the start of a new initiative in whale and dolphin research in Oman. The Oman Whale and Dolphin Research Group, a group of volunteer scientists, gained official approval from the Ministry of Regional Municipalities and Environment, enabling them to conduct more focused research on the whales and dolphins found in the Sultanate of Oman. A grant from the Ford Motor Company helped to get the project off the ground, and as it gathered momentum, a number of local businesses made important contributions to facilitate the research. PDO and Salalah Port Services provided a boat, fuel, logistic support and accommodation. Emirates Airlines, Kenya Airways, Oman Air and KLM sponsored travel for visiting scientists and conference attendance. Truck Oman transported the research boat and equipment between Muscat and Salalah. DHL, Mark Rental Cars and WS Atkins donated their services and a number of companies, including OHI Marine, Tawoos, Veritas Geophysical, Oman LNG, Muscat Pharmacy, Elcome International, Cameron, and Tarmac Alawi donated goods and equipment

With this valuable support, the researchers were able to enlist the help of internationally renowned whale and dolphin experts on a number of surveys between February 2000 and June 2001. In between these planned surveys, members of the research group carried out opportunistic work in the Muscat area, taking every possible opportunity to survey beaches or carry out boat-based observations. They have also developed a website, attended conferences and open-days and published articles in local media to raise local awareness and encourage members of the public to become involved in cetacean research by reporting their sightings of live, entangled or stranded animals.

This report is intended to provide sponsors and other interested parties with information on the group's activities during the 2000-2001 field season.

 

Surveys in the 2000-2001 field season ^^

In October 2000 the group spent seven days in the Mahoot region with a group of British "eco-volunteers," tourists who came to Oman to participate in local conservation efforts. The team collected over 20 dolphin skulls in four days, and measured and photographed a number of baleen whale skulls that were too large and bulky to collect. During the three days that sea conditions permitted boat-based surveys, several humpback and Bryde's whales were studied and photographed. The images were the among the first to be entered into the Sultanate's "humpback whale photo-identification catalogue," a collection of photographs of tail flukes and dorsal fins, which will allow researchers to recognise individual whales if they are seen and photographed again in the future. "Re-sights" of known individuals can give an indication of whales' seasonal movements.

In February 2001, team was joined by Dr. Ken Findlay, a South African humpback whale expert. Using a 6.5m rigid hulled inflatable boat donated by PDO and Salalah Port Services, the researchers surveyed over 1000km of the coastal area between Salalah and Hasik, including the Hallaniyat Islands. The first humpback wasn't sighted until the fourth day of the study but the sighting was worth the wait. The whale was feeding, confirming that the nutrient-rich Dhofari waters are an important feeding ground for this species. More surprises were in store when it lifted its tail to dive (called 'fluking'). The researchers were stunned to recognise it as one of the animals that they had observed two months previously in the Muscat area. This first re-sight of a previously photographed individual also provided a first clue about the whales' movements in Oman.

Throughout the rest of the two-week study period, hundreds of dolphins, a blue whale, 20 sperm whales and ten more humpback whales were observed and photographed. The team also recorded humpback whale song using a hydrophone donated by the Sultan's School. Male humpbacks sing during the breeding season, and the recording provided a strong indication that the Dhofar region serves both as a breeding area and a feeding ground. This overlap of feeding and breeding has not yet been documented for humpback whales in any other part of the world. They normally feed in low latitudes, near the poles, and breed in the tropics, and the two activities are separated by several months and thousands of kilometres.

The last humpback whale sighting of the Dhofar survey was just as exciting as the first, as this whale treated the observers to the spectacle of a breach (a leap into the air). Nothing compares to the thrill of watching a 20-ton creature launch itself out of the water, slowly arch to the side and thunderously splash back down. For the researchers, this act had the added scientific value of providing skin samples for genetic analysis. Following these types of high-energy activities, it is possible to use a sieve to scoop up sheets of skin that are shed as the whale splashes down through the water. Like the skin samples collected from dead animals on beaches, these will be sent to laboratories in the United States for detailed genetic analysis that should reveal whether Oman's humpback whales are related to other populations in the Indian Ocean

Shore based observation, Duqm

In March, a short research trip to the Ras al Hadd area, facilitated by Oman LNG, yielded valuable observations of dolphins at sea, as well as the opportunity to survey some remote beaches for cetacean remains. A number of skulls were collected for the Oman Natural History Museum, including two relatively rare dwarf sperm whale skulls (Kogia simus) that were found wrapped in a fishing net.

In June 2001, the research team were joined again by Dr. Ken Findlay, who introduced them to a shore-based observation technique that utilises a surveyor's theodolite (provided by W.S.Atkins) to track the movements of whales offshore. Setting up a camp on a high cliff, the team spent four days practising the technique. When whales and dolphins were sighted, the team used the theodolite to accurately record the animals' positions and direction of travel. Although some surveys using this technique have detected whales 18km from shore, the early phases of the monsoon gave rise to hazy conditions that limited visibility during the Duqm survey. In total, the study yielded 15 dolphin sightings, and ten whale sightings, providing an important clue to the whales' whereabouts during a time of year when seas are too rough for boat-based observation.

In the second half of May, world renowned dolphin expert, Dr. Koen Van Waerebeek visited Oman for the third time. During previous visits he had studied the taxonomy of Oman's dolphins, and attended the International Whaling Commission's annual meeting, which was held in Muscat in 1998. Over 150 skulls had been added to the Natural History Museum's collection in the five years since he had last examined them and he declared the collection 'one of the best in the Indo-pacific region.' Nearly every morning of his two-week visit was spent carefully measuring and cataloguing the skulls of over 100 spinner, common, Indo-Pacific humpback, and bottlenose dolphins. These measurements will be compared with other populations of the same species in an attempt to determine how Omani populations are related to those elsewhere. During a brief survey of beaches in Mahoot, Van Waerebeek also shared his expertise in working with stranded specimens, helping the team to analyse dead dolphins and skeletal material.

Public awareness and dissemination of information ^^

During the course of the past 18 months the research group's work has been covered in over ten separate newspaper articles in the English and Arabic Daily newspapers. It has also featured in several issues of PDO's "Al Fahal", and the regionally distributed "Oman Today". Members of the team have also published articles in the annual "Tribute" magazine and quarterly "Arabian Wildlife".

The Group attended and presented information at several local and international gatherings, including: a PDO open day in November 2000; an international conference on fisheries and marine resources, hosted by Sultan Qaboos University in January 2001; an open day at Sultan Qaboos University in April 2001; a workshop on regional cooperation in humpback whale research hosted by Cape Town University in April 2001, and a lecture organised by the Historical Association of Oman in May 2001.

Website ^^

With the help of a dedicated volunteer "webmaster", Russell Elliott, the group has set up it's own website: http://www.whalecoastoman.com. The website features information on the group's activities and sponsors, as well as more general information about cetaceans in Oman. The website is regularly updated with new photos and reports and has received over 500 "hits" since February 2001. Visitors to the website have come through internet providers from around the globe, including the United States, New Zealand, South Africa, and Malaysia.

Local participation and training ^^

Members of the group talk extensively with local fishermen and community members in the areas where they have worked. In areas that have been visited on several separate occasions (such as the Hallaniyat Islands), researchers have shared photographs and audiotapes with local schools.

Recently, the research group has been able to involve a student in his final year of fisheries studies at Sultan Qaboos university, as well as an employee of the Ministry of Agriculture and fisheries. The group plans to continue with this cooperation, and to intensify efforts to involve more local participants and trainees in its work in the next field season.

Financial Accounting ^^

The group has kept detailed accounts of sponsors' donations and outgoing expenses. These accounts are reviewed twice a year by a local accounting firm, KPMG. More detailed financial statements will be available to sponsors upon request.

Data and results ^^

The data and results of the team's studies will be presented to the Ministry of Regional Municipalities, Environment and Water Resources, so that these data are available for implementation in conservation and management decisions. Although the research team is independent, they work in close consultation with MRMEWR and have approval from the Director General of Conservation and nature Protectorates for their research.

2001-2002 field season ^^

The next research season will run from October 2001 through June 2002 and will involve at least two Omani recruits. This work will only be possible, however, if more funds can be raised. A detailed research proposal and budget for the 2001-2002 field season is available upon request.
