Estimated learn time: 4-5 minutes

PROVO — David Lengthy was a professor at Brigham Younger College in 1999, utilizing a satellite tv for pc distant sensor to check sea ice, tropical forests and icebergs — when he and his college students by chance stumbled upon a misplaced iceberg.

“I needed to name the Nationwide Ice Middle to seek out the title of this iceberg. … After some time, they got here again and mentioned, ‘Oh, that is iceberg B10A, which is an iceberg that we had been monitoring and we misplaced observe of it 4 months in the past. You discovered it — it is in a transport lane,” Lengthy, a professor {of electrical} and laptop engineering, recounted.

He then started offering the middle with all of the iceberg monitoring information he may discover, utilizing his scatterometer.

“That is how we obtained began in icebergs, and since that point, we have continued to keep up our iceberg database,” Lengthy mentioned. “It was kind of serendipitous.”

The iceberg he and his college students found was greater than the Utah Valley. The chunk of ice would stretch from Nephi to Bountiful, measuring 60 miles lengthy and 20 miles extensive.

Now, 24 years later, Lengthy was a part of a research evaluating present observations of enormous Antarctic icebergs with explorer observations within the 1700s, utilizing trendy satellite tv for pc datasets, exhibiting the large icebergs are present in the identical areas they had been pinpointed in three centuries in the past.

Utilizing primarily the journal data of Captain James Cook dinner’s 1772-1775 Antarctic circumnavigation on the HMS Decision — through which he famous the positions of a whole lot of icebergs — Younger, together with researchers from NASA’s Jet Propulsion Laboratory and the College of Washington’s Faculty of Oceanography made comparisons with the 2 largest trendy information units accessible in the present day: the BYU/Nationwide Ice Middle and Denmark’s Alfred Wegener Institute information units.

“In actuality, that is extra of a human curiosity story than it is a vital scientific end result,” Lengthy mentioned.

The group’s current discoveries confirmed that regardless of the outdated and tough strategies utilized by 1700-era explorers, these explorers had been in a position to precisely decide the placement of icebergs; and iceberg motion patterns have behaved persistently for greater than 300 years.

They are not the identical actual icebergs noticed three centuries in the past, Lengthy mentioned, however they’re breaking off from glaciers and shifting by the ocean in related patterns as they had been within the 1700s.

Seelye Martin, Lengthy’s co-author within the research, extracted Cook dinner’s iceberg observations from a line-by-line search of Cook dinner’s journal-turned-book about his journey: “A Voyage In the direction of the South Pole, and Around the World.”

Martin, Lengthy and one other co-author, Michael Schodlok, then in contrast the positions of the icebergs famous in Cook dinner’s journals of the iceberg plume east of Antarctica’s Amery Ice Shelf — together with iceberg distributions within the Weddell, Ross and Amundsen seas — with trendy information.

“We discovered that they are usually in settlement, which is sweet, as a result of that kind of (reveals) that icebergs in the present day will not be so completely different from ones again then, 300 years in the past,” Lengthy mentioned. “We added these collectively, and that is when the cloud of factors type of matched up between what these outdated explorers noticed and what we see now.”

Lengthy, a famous fan of puns round BYU’s campus, mentioned that he likes to make use of the phrase “cool” when describing the sensation his group had once they realized the information units had been in settlement, noting that his description is “type of redundant when speaking about icebergs.”

“Scientists are principally working, type of, on arduous work, and plenty of what I do is type of tedious and boring — taking a look at these footage, establish the icebergs and observe the place they’re and go to the subsequent image,” Lengthy mentioned. “If you get to see it apply and compared to one thing like this, it is actually type of enjoyable.”

Lengthy’s greatest takeaway from his analysis endeavor?

“You by no means know when your journal can be helpful,” he mentioned, referring to Cook dinner’s data.

“He was recording one thing that was type of trivial in his thoughts — seeing some ice within the water. As soon as you’ve got seen it a few times, it is like, ‘Eh, I need not write that down,’ however he stored doing it and since he did that, we now have this information and it was helpful,” Lengthy mentioned. “Who may’ve thought that one thing that any person wrote 300 years in the past would nonetheless be helpful in the present day, 300 years later?”

The analysis was printed final month within the Cambridge College Press Journal of Glaciology.

Utah Highway Patrol responds to your suggestions on making Utah roads safer


SALT LAKE CITY — FOX 13 News is Driven to Change and that includes bringing you reports on important topics like road rage, construction, and wrong-way drivers. During our coverage, we continually ask for any questions or concerns you may have along Utah’s roadways.

The feedback has gotten an enormous response, so FOX 13 sat down with Lieutenant Cameron Roden on Good Day Utah to help address input we have been getting, from the perspective of Utah Highway Patrol.

Speeding in Utah, there’s so much of it, and then you can sometimes say that that leads to tailgating, which may lead to road rage incidents. What are you seeing out there in terms of speed and what can we do to lessen the effects of that?

Lt. Cameron Roden: Speed is our number one thing that we see. That’s our number one traffic stop that we make, and we know that it leads to the majority of crashes in the state of Utah. So we definitely put an emphasis on speed and it does lead to other things. Not just crashes. It leads to road rage and other things .So, as far as what changes can we make, we need to start with ourselves, and really say, ‘Hey, do I have a problem?’ You know, we just need to start with ourselves and not think that it’s something else’s problem. If we slow our speeds ourselves, and then it’ll start to to catch on and people will do that speed limit. So, but the legislature has definitely taken some steps to help us address, especially the the speeds that are those excessive speeds where we have that one zero five law now that addresses those speeds and increases fines and and hopefully discourages people from those extreme speeds.

Some of our viewers talked about maybe capping some of the speed limits for truck drivers. Is that something that’s even feasible?

You know, that would be something that would have to go through that, that legislative process to see whether we that would be something that would help. But ultimately, if we we start with ourselves, hopefully that will make that change and reduce crashes and fatalities.

There are things being done to try and intervene and stop wrong-way drivers before they happen. But some of our viewers propose things like spikes. What are your thoughts on implementing something like that?

We’ve had over the last several years, a rash of wrong-way drivers, and it’ll come in onesie twos, and then we’ll go for a period of time without that. And so, but this spike over the last couple of years has caused us to to create a task force to look at wrongly driving what things can be done. And so getting all these stakeholders together between UDOT and Highway Safety, looking at what technologies and things that could be implemented, and and things like, wrong way detection cameras. Those are some things that are being actually used in the state of Utah right now to help us spot those and and advance signage, getting people to realize they’re going the wrong way and turn around. The the spike strips have actually been talked about in our task force a little bit. And if something like that would even be, it is that technology available right now. And as what we could actually implement in the state of Utah, there’s nothing that really fits the bill right now because of our environment. We have our snow plows. We have snow and things like that. Something like that really wouldn’t be practical right now.

Probably the most talked about topic that we’ve received was distracted driving, texting while driving. You went out, I saw on the UHP social media page, that you guys just driving and you look to your right and left and you can find someone texting. What kind of enforcement do we have against distracted driving specifically on your phone?

This is something that we like you said, we see it every day. We go out to crashes,and and we may suspect that a driver may be distracted. And so, it’s something that’s definitely under-reported. It’s it’s a bigger problem than than the numbers really show.And so not only do we address it during our normal patrols.Our officers are seeing it, and addressing it while they’re out there.But we’ll also do targeted patrols where the highway safety office actually gives out additional funds for that targeted enforcement, where we’ll get an unmarked vehicle. We go out driving down the roads where we try to spot these vehicles and and get them stopped because those are those are a big danger on our roadways where our attention and our focus needs to be on driving.

Utah National Guard gets new, top-of-the-line Apache helicopters


WEST JORDAN, Utah — The Utah National Guard has been serving the state since 1894 with roots dating back to the Minutemen of the 17th-century American colonies.

This weekend, they received quite the boost in the form of the Army’s most advanced attack helicopter.

“These aircraft are extremely fast compared to our other aircraft,” said Col. Patrick.

On Saturday, the Utah National Guard took their new Apache helicopters for a spin.

“The flight went better than we could have hoped for. A little weather on the east coast, but after that, it wasn’t bad at all,” Patrick said.

The first four of 24 Apaches arrived early Saturday morning after they went under full inspection.

“They’ve got software on there that it’s like playing a video game. You just fly the video game and the airplane… is fast and smooth, which is the good thing, and so it’ll just hold the altitude and airspeed and just keep on trucking along. It’s pretty good,” Patrick said.

The first Apache helicopters arrived in Utah back in 1992.

“It just continues the legacy of the air pirates and what we bring to not only Utah, but really to the global fight and security, really,” Patrick added.

The colonel calls it a major step forward.

“What a great day for Utah as we advance into the next couple decades of combat operations and what we can provide to, you know, the global security.”

Toronto Maple Leafs vs. Utah Hockey Club – Game #21 Preview, Projected Lines & TV Info


The depth continues to be tested as the bodies keep dropping out of the lineup up front. Tonight, a resilient Maple Leafs team is seeking its fourth consecutive win as Alex Nylander debuts on an all-Marlies line against a tired 8-9-2 Utah Hockey Club (7:00 p.m. EST, TSN4).


Head-to-Head Stats: Maple Leafs vs. Utah

In the 2024-25 regular season statistics, Utah holds the advantage in three out of five offensive categories and three out of five defensive categories.


Game Day Quotes

Craig Berube on what he learned from the pre-scout of Utah’s 6-1 win over Pittsburgh last night: 

The power play was good. They got three. They’re fast, and they have a lot of skill. They make a lot of plays — a lot of west-west plays — and get up the ice really well. Their D are involved.

We have to check well tonight. We have to stay out of the penalty box. Our PK is going to be important.

Overall, we need to take time and space away from this team right out of the offensive zone. Be hard on them breaking plays up. That will be very important tonight.

Berube on the decision to start Joseph Woll over Anthony Stolarz tonight: 

[Woll] had a really good game against Vegas. We are just thinking ahead here. Stolly has played a lot. We have some time here. He is working in practice and doing a lot of good things.

That’s really it. We just talk about things and make decisions on what we think is best for the goalies and the team.

I talked earlier about how both goalies are going to see more net than they have in the past. It is important that we manage it to the best of our abilities.

Woll is coming off a real solid game against a real good team. We wanted to go back with him.

Berube on what improvements he is looking for from his team offensively after a week of practice: 

Attacking more than we are. There are times when we tend to just control the play a little bit too much on the outside. We could attack more with more shots to the net, get pucks low to high, and do more on-and-off shooting while getting people to the net with numbers around there.

Resets to the back of the net, making quick plays out of there, doing things a little bit quicker, moving it quicker, supporting it quicker, and getting more pucks to the net than we are.

Berube on why Fraser Minten is so trustworthy despite his lack of experience:

It goes back to a great draft pick, finding a player who is so responsible at a young age. You guys aren’t on the bench, but just hearing him talk on the bench and how he sees the game, he says all the right things.

You don’t see young guys do that very often. He is already doing it at a very young age with very little experience. It is great to see. It’s refreshing. It really is.

Minten on the keys to success for his line with Nikita Grebenkin and Alex Nylander:

We just have to be simple with pucks and forecheck, using our speed to get pucks back on the forecheck. From there, let the skill make things happen. Those guys are really good when they get it back, so we have to make sure we are forechecking hard to retrieve pucks, and we’ll go from there.

Minten on the keys to success in the net-front role on the top power-play unit: 

Try not to overcomplicate it too much. Get the goalie’s eyes, get in sight lines, try to get pucks back, get some tips, get some screens, and cause a little chaos. You can draw a defender with you. If you’re going backdoor, you give them a little more space. Be ready for anything coming to you. They are great players, so just try to read off of them, and hopefully, it goes well.

Minten on his experience level in front of the net on the power play: 

In junior, I was mostly a flank guy with the puck more, but last year, I kind of got into it more at the end of the year, and I have been playing that role with the Marlies every game so far this year.

Minten on Morgan Rielly’s guidance at the NHL level:

He has been amazing. We have a lot in common, being from the same place. He took me under his wing a little bit and has been super nice. It makes it easy when you are coming in at 18 or 19 and there is a guy who comes to talk to you and is a really nice, supportive guy and friend. He has been awesome.
