Failure to communicate: US Navy seeks faster data transfers amid Arctic ice

WASHINGTON — Research in the Arctic Ocean is no small feat. The area can prove inaccessible at times, and sensors can fail to communicate data from under the ice or get crushed by slabs of ice.

But with the Arctic getting warmer and ice melting at an accelerated rate, the U.S. Navy is preparing to operate in newly available waterways. To do that effectively, the service knows it will take intense research to create durable, innovative solutions that can withstand harsh conditions, while also relaying data to researchers.

“If the Navy's thinking about having to run operations up there with submarines, surface vessels and aircraft, you really need to understand that operational environment,” Scott Harper, the Office of Naval Research's program manager for Arctic and global prediction, told Defense News in a May 4 interview. “Where is that sea ice and how quickly is it retreating? And what is it doing to the upper water column in the ocean?

"To really understand all that, you need to have a lot of observations.”

Navy and academic researchers are working together to improve the service's forecasting models in the Arctic. The Navy currently has research buoys, sensors and other technology floating in the water to track a variety of metrics: waves, atmospheric and water circulation, sea ice thickness and cover, speed at which the ice moves, and several other factors. All those metrics factor into Arctic forecasting.

In order to improve its forecasting capabilities, the Navy needs to improve its numerical models, or complex equations used in predictions. But to do that, the service needs more up-to-date data.

“These numerical models are kind of like balancing your checkbook,” Harper said. “You need to start with what your current checking account balances [to[ if you're going to predict what it's going to be at the end of the month. And so even if you had a perfect numerical model that you could use to make a forecast, if you don't know what the conditions are right now, you're not going to be able to forecast what the future state is going to be.”

To do this, the Navy wants to more quickly collect data through an effort called the Arctic Mobile Observing System, or AMOS. The program aims to create near-real-time data transmission of the sea condition under the ice, and communicate that information to the Navy via satellite.

“You have satellites that can look down at the surface of the Arctic Ocean and the sea ice conditions,” Harper said. “But what we don't have [is] the ability to look under the ice and understand what the ocean conditions are, and that's what we're really trying to enable with Arctic Mobile Observing System prototype.”

The AMOS program has deployed gliders underneath the sea that are collecting and storing data about the oceanic conditions under the ice, and tracking the location of frozen water using acoustics. In a few months, Harper said, researchers will send an icebreaker to the Arctic and gather the data collected by the gliders.

The Office of Naval Resarch, however, would like to bypass the multi-month delay involved in collected the data. To do so, the office plans to enable two-way communication so underwater sensors can communicate data via floating buoys in the ice that, in turn, communicate the data via satellites back to the Naval Oceanographic Office.

The project is currently two years into the five-year project. According to the project website, it's slated to end in fiscal 2023 with the recovery and evaluation of the initial prototype in the late summer of 2023.

Harper said the project's biggest success has been the navigation system that's currently working underneath the ocean surface.

“The fact that we can put sensors out that will know where they are without having to come to the surface to get a GPS fix — because they can't come to the surface because there's sea ice there for nine months out of the year," he said. "That's a big win.”

Another critical component to the real-time data collection are the buoys that ultimately must be able to survive the cruel nature of Arctic ice. The AMOS team has deployed prototypes of “ice-hardened” buoys that survived “multiple months” in the Arctic environment, Harper said, paving the way for a fully equipped communications buoy that can talk with underwater sensors.

“You can go out there and you can put your sensors in the ice, but a lot of times they'll fail,” Harper said. “And they'll fail because they'll get crushed in the ice or tipped over or toppled by changing ice conditions. And so the ability to deploy a buoy that is robust enough to survive the sea ice is one of the technological hurdles to doing this.”

  • COVID-19 Federal Funds, Benefits Lag For National Guard

    COVID-19 Federal Funds, Benefits Lag For National Guard

    President Trump has authorized only 34 states to receive federal funding and benefits for their Guard troops. While all of them get paid -- many out of rapidly depleting state coffers -- most aren't yet getting full health coverage. By SYDNEY J. FREEDBERG JR WASHINGTON: Legal arcana and the narrow wording of President Trump's orders are complicating the mobilization of National Guard troops to combat the COVID-19 coronavirus. The Pentagon, the White House, and the states are working urgently to increase the number of troops with federal funding and full benefits, said Gen. Joseph Lengyel, the four-star chief of the National Guard Bureau, in a phone briefing with reporters this afternoon. Part of the problem is that President Trump has not actually authorized federal funding and benefits for every state. Only 34 states and three territories are currently covered by his call-up orders, with 16 states and the District of Columbia still ineligible. (The full list is at the end of this article). Indeed, it's not clear that all states have even requested federal support for their Guard troops, especially in rural areas where the spread of the virus has been slower and suspicion of the federal government can be high. Even once the president authorizes a given state, FEMA must still approve each request for funding. Finally, until yesterday, President Trump's orders only permitted Guard troops to operate under federal orders for up to 30 days – one day too short to qualify for federal health coverage and other benefits. So how many servicemembers are affected? 28,400 personnel from both the Army and Air National Guard have been called up to help with the pandemic, Lengyel reported, a figure that's now rising by more than 1,000 troops every day. However, more than 13,000 of those troops are currently mobilized under state legal authorities, at their states' expense. While their pay in this status is usually consistent with federal payscales — some states are less generous – their benefits are typically limited to basic workers' compensation. Worse, whatever they get may not be sustainable since state coffers are being rapidly depleted by the crisis. Not quite 11,000 are currently mobilized under Title 32, Section 502(f), which allows state governors to retain command-and-control of their Guard in local emergencies but provides federal funding – a number that is “growing rapidly,” Lengyel said. But even among Guard troops on those federal Title 32 orders, it appears that most don't yet enjoy the same benefits as members of the regular active-duty military and reserve working alongside them. In particular, most Guard troops aren't getting the Basic Allowance for Housing (BAH), which helps troops on duty far from home pay for lodging if the military can't provide it, and they don't get access to the military's nationwide healthcare network, Tricare. (Guard troops can go to military hospitals for free, but few of the coronavirus hotspots they've been called to are anywhere near a base). Some 349 Guard troops have tested positive for COVID-19, although many of those were infected in civilian life and aren't being called up. Why aren't all troops on federal orders already? And why aren't all the troops on federal orders getting full benefits? That has to do with the often-obscure laws governing the National Guard and the way President Trump has chosen to invoke them. First, Trump hasn't yet authorized federally funded Title 32 call-ups across the country. Instead, on March 22, he authorized them only for Washington State, California, and New York – the three initial hotspots – and then began adding states a few at a time in subsequent orders on March 28, March 30th, April 2nd and April 7th. “FEMA generally gives shorter duration mission assignments, normally two weeks,” Lengyel explained, since most domestic disasters take less than a month to resolve. “We in the National Bureau and the Department of Defense saw this [coronavirus] clearly is going to go into May and maybe beyond, [but] FEMA was restricted [in] writing the mission assignments to what was authorized in the presidential memorandum. “I don't want to speculate on why they chose 30 days, but the difference between 30 and 31 is significant,” the general said. “We recommended a longer period of time at the beginning.” The National Guard Association of the US, an influential independent advocacy groups for Guard units, members, and families, has been watching the situation intently and pressing for an expansion of the Title 32 orders. Consistency has been lacking, lamented John Goheen, NGAUS's chief spokesman: “It's really a patchwork as you look around the country, and states are going to interpret things differently. “Section 502(f) of Title 32 was never designed for this. As a result, we are seeing of lot of bureaucratic obstacles and inflexibility,” Goheen told me this afternoon. “Case in point is the limitation on the number of days. NGAUS will be looking to change the law in the future to provide more flexibility.” The last time Title 32 was used on such a scale was Hurricane Katrina, Goheen said “There were some concerns [after Katrina] about the Defense Department being reimbursed so the Defense Department's been reluctant to use it,” he said. However reluctant the Pentagon bureaucracy in general may be, Gen. Lengyel made clear he is trying to fix the situation. “We're authorized now to bring on up to 44,000 total members of the National Guard covered under ...Title 32 ... which gives them federal pay but state control, and now — because the [April 7th] memorandum allows them to be covered for up to 31 days — they will have full insurance and medical benefits,” he said. But troops who were authorized earlier on shorter orders will have to be switched to 31 days, and making sure all new call-ups are for 31, is an ongoing process, Lengyel acknowledged: “There was some sand in the gears on making sure that we had the cost figures right so that FEMA had the exact numbers.” Meanwhile, he said, his staff and the states have started planning for the annual hurricane season. “By hurricane season, which starts in June, obviously, we're hopeful this begins to lull,” he said, “[but] we in fact are looking at implications of what it might be like to do a hurricane response in a COVID environment.” His staff and the states Guard headquarters, he said, are conducting their planning by telephone and video-teleconference (VTC) instead of the usual in-person meetings. Below is the full list of which states President Trump authorized for federally-funded National Guard callups, by date: March 22, three states: California, New York, and Washington. March 28, five states and two territories: Florida, Louisiana, Maryland, Massachusetts, and New Jersey; Guam and Puerto Rico. March 30, three states: Connecticut, Illinois, and Michigan. April 2, 10 states, one territory: Georgia, Hawaii, Indiana, Missouri, New Hampshire, New Mexico, Ohio, Rhode Island, Tennessee, and Texas; US Virgin Islands. April 7, 13 states: Arizona, Colorado, Kentucky, Mississippi, Montana, Nevada, North Carolina, Oregon, Pennsylvania, South Carolina, Virginia, Wisconsin, and West Virginia. https://breakingdefense.com/2020/04/covid-19-federal-funds-benefits-lag-for-national-guard
