Researchers from UVic, Spain study Antarctic Ocean

Published

 on

University of Victoria-based scientists are teaming up with their Spanish peers to study the Antarctic Ocean, following an international plea for more work to be done there.

UVic’s Ocean Networks Canada, which operates underwater observatories off the country’s Pacific, Atlantic and Arctic coasts, will be working with the Spanish National Research Council at its Antarctic station.

As with its existing observatories, ONC’s Antarctic version will include sensors connected to cables on the ocean floor.

It will be the first time ONC has done subsea research beyond Canadian waters.

ONC and its Spanish counterparts announced their partnership this week, and cited a recent call from 300 scientists in 25 countries for an “urgent expansion” of observation in the Antarctic Ocean, also known as the Southern Ocean.

A joint statement from the scientists in December said there is a “chronic lack” of work being done in the area.

David Hik, chief scientist for Polar Knowledge Canada — which manages Canada’s scientific contributions and commitments to the Antarctic Treaty — said the partnership between Canada and Spain is an important milestone in ocean monitoring.

Chief executive Kate Moran said ONC has operated in the harsh polar conditions in the Arctic since 2012, so it has the expertise to contribute to Spain’s ongoing work around Antarctica and the Antarctic Ocean.

She called Antarctica “a continent that is critical to this planet’s climate system” and said it is undergoing “rapid, consequential changes” that must be understood.

The ONC’s new observatory there will produce data on a range of ocean conditions, and monitor seawater quality where the ocean and glacier melt come together.

Sensors include equipment to measure temperature, oxygen concentration and chlorophyll levels on the water.

The Spanish polar-research vessel Hespérides is en route to the Antarctic station with the material to build the observatory, and is scheduled to arrive there this month.

“This partnership with Ocean Networks Canada will provide vital ocean science data in the Southern Ocean, not least because the new observatory will operate year-round outside of the station’s staffed summer months,” said Jordi Sorribas Cervantes, director of the Unit of Marine Technology for the Spanish research group.

“Having access to this near-continuous data, from anywhere in the world, will help meet the current data gap challenge in the Southern Ocean.”

The proposed location for the observatory, modelled after one of the ONC observatories in the Arctic, is in a small bay at a depth of 23 metres in the South Shetlands Archipelago — north of the Antarctic Peninsula.

The ONC said its research partnership fits with UVic’s commitment to the United Nations’ sustainable-development goals and to the university’s focus on climate action.

“It’s exciting to see ONC’s transformative leadership in ocean science expand internationally to inform climate solutions beyond Canada’s three coasts,” said Lisa Kalynchuk, UVic’s vice-president of research and innovation and a member of the ONC board. “This partnership demonstrates how coastal communities and scientists from around the world can drive technological innovation and scientific discovery.”

ONC observatories function in both the deep ocean and coastal waters with Internet connection to scientific instruments, cameras and 12,000-plus ocean sensors.

That includes the NEPTUNE observatory off the B.C. coast, made of up over 800 kilometres of cable at depths up to four kilometres.

ONC made its first foray into subsea research in 2006 when a telecommunications device was lowered to the bottom of Saanich Inlet, and the world’s first fibre-optic cabled ocean observatory soon followed.

Data collected includes information on the chemical, biological and geological aspects of the ocean. ONC offers programs for students from kindergarten to Grade 12 and those in graduate school, and for groups in the community.

Underwater cameras were added to the system in 2013 and eight deep-sea seismometers were installed in 2018 as part of B.C.’s earthquake early-warning system.

In 2022, ONC was awarded $114.8 million over six years through the Canada Foundation for Innovation’s 2023 Major Science Initiatives Fund to support operating and maintenance costs.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

This report by The Canadian Press was first published Sept. 9, 2024.
