This month J&G will complete the installation of a second and entirely new grinding line to accommodate future customer demand.

The company brought on the new grinding line for increased capacity, flexibility, redundancy and peace of mind.

Additionally, the grinding line will give the company the ability to bring on value added products, items that include ground meats along with other ingredients, such as meatloaf, meatballs, bacon - cheddar burgers, for example.

Every line except a ground line needs a float, and so does the running ground line; but not the lying ground line.

For the float on a lying ground line, 10 weights joined together; for the running ground line, nine or 10 small ones.

You may angle for him at all times with a running or lying ground line; except in leaping time, when you use an artificial fly.

The hope is that the cables could reveal secrets about what's happening underneath the ice sheets, especially about melting at the so - called grounding line, the place where the bottom of an ice sheet meets the slightly warmer ocean.

Some glaciers on the perimeter of West Antarctica are receiving increased heat from deep, warm ocean currents, which melt ice from the grounding line, releasing the brake and causing the glaciers to flow and shed icebergs into the ocean more quickly.

Melting would make the grounding line retreat — this is where the ice on the continent meets the sea and starts to float.

Eventually, the floating ice shelf in front of the glaciers «broke up», which caused them to retreat onto land sloping downward from the grounding lines to the interior of the ice sheet.

The height of these cliffs made them unstable, triggering the release of thousands of icebergs into Pine Island Bay, and causing the glacier to retreat rapidly until its grounding line reached a restabilising point in shallower water.

Satellite data also helped them make a detailed map of grounding lines across Antarctica and determine where glaciers were retreating fastest.

The boundary between glacier and ice shelf is called a grounding line.

They found that, as seas warmed at the end of the last ice age, Pine Island Glacier retreated to a point where its grounding line — the point where it enters the ocean and starts to float — was perched precariously at the end of a slope.

These surface height data can help scientists pinpoint changes in the location of the grounding line.

At the grounding line, the ice detaches from the bedrock and juts out into the water as a kind of floating ledge, or ice shelf, which helps to stabilize the glacier and hold back the flow of ice behind it.

The position of the grounding line can tell scientists a lot about the stability of any given glacier and its potential to contribute to sea - level rise.

There, 22 percent of the grounding line is retreating faster than the benchmark 80 feet per year.

For now, the findings can't tell scientists exactly how much sea - level rise is corresponding with the observed changes, although a net retreat of the grounding line suggests that there's more reason for worry than not.

But overall, the Antarctic grounding line has experienced a net retreat.

At Pine Island Glacier, for instance — one of West Antarctica's largest glaciers, and previously one of its fastest retreating spots — the research suggests that the grounding line has recently stabilized.

But scientists increasingly attribute much of the observed grounding line retreat — particularly in West Antarctica — to the influence of warmer ocean water seeping beneath the ice shelves and lapping against the bases of glaciers, melting the ice from the bottom up.

The team were able to track the movement of Antarctica's grounding line using European Space Agency's CryoSat - 2 across 16,000 km of the coastline.

The retreat of the grounding line at these glaciers is more than five times that rate.

Although CryoSat - 2 is designed to measure changes in the ice sheet elevation, these can be translated into horizontal motion at the grounding line using knowledge of the glacier and sea floor geometry and the Archimedes principle of buoyancy — which relates the thickness of floating ice to the height of its surface.

Research by the UK Centre for Polar Observation and Modelling (CPOM) at the University of Leeds has produced the first complete map of how the ice sheet's submarine edge, or «grounding line,» is shifting.

Study co-author Professor Andy Shepherd, from the School of Earth and Environment at Leeds, said: «We were delighted at how well CryoSat - 2 is able to detect the motion of Antarctica's grounding lines.

Grounding lines typically lie a kilometre or more below sea level and are inaccessible even to submersibles, so remote sensing methods for detecting them are extremely valuable.

Most Antarctic glaciers flow straight into the ocean in deep submarine troughs, the grounding line is the place where their base leaves the sea floor and begins to float.

Although retreat of the Thwaites Glacier grounding line in West Antarctica has sped up, at the neighbouring Pine Island Glacier — until recently one of the fastest retreating on the continent — it has halted.

Between 2002 and 2007, satellite measurements showed that ice from the glacier's grounding line, the spot where it transitions from being on the land to in the sea, thinned at a rate of 1.2 meters to 6 meters per year.

«If protective ice shelves were suddenly lost in the vast areas around the Antarctic margin where reverse - sloping bedrock (where the bed on which the ice sheet sits deepens toward the continental interior, rather than toward the ocean) is more than 1,000 meters deep, exposed grounding line ice cliffs would quickly succumb to structural failure as is happening in the few places where such conditions exist today,» the researchers point out.

Now seafloor sediments reveal that Larsen B's grounding line had remained stable for thousands of years before the ice shelf's collapse.

The finding demonstrates that the grounding line wasn't involved in Larsen B's breakup, says study coauthor

As Hartmut Hellmer explains, «When it comes to the Amundsen Sea, where warm water has already reached the continental shelf and even the grounding line of some ice shelves, we can safely say that this inflow of heat can not be stopped; the climate regime change has already taken place.

As a result of the dramatic melting on its underside, the shelf's grounding line will shift further south and the ice will gradually lose direct contact with the seafloor.

If they begin to melt, however — particularly as they're exposed to warmer ocean water — the shelves become thinner and the grounding line begins to retreat backward, causing the glacier to become less stable and making the ice shelf more likely to break.

Lead author Dr Malcolm McMillan from the University of Leeds said: «We find that ice losses continue to be most pronounced along the fast - flowing ice streams of the Amundsen Sea sector, with thinning rates of between 4 and 8 metres per year near to the grounding lines of the Pine Island, Thwaites and Smith Glaciers.»

The ice is firmly grounded to the bedrock, up to a point known as the «grounding line.»

If a glacier loses mass from enhanced melting, it may start floating farther inland from its former grounding line, just as a boat stuck on a sandbar may be able to float again if a heavy cargo is removed.

Smith's retreat might slow down now that its grounding line has reached bedrock that rises farther inland of the 2014 grounding line.

For a separate study, the NASA Jet Propulsion Laboratory's Ala Khazendar — a co-author of Scheuchl's paper — measured ice loss at the bottom of the three glaciers, which he suspected might be influencing the changes in their grounding lines.

Radar waves penetrate glaciers all the way to their base, allowing direct assessment of how the bottom profiles of the three glaciers at their grounding lines differed between 2002 and 2014.

The Pope Glacier's grounding line receded more slowly, at 0.31 miles (0.5 kilometers) annually since 1996.

The grounding line is important because nearly all glacier melting takes place on the underside of this floating portion, called the ice shelf.

Khazendar and his team, analyzing their direct radar measurements, found stunning rates of ice loss from the glaciers» undersides on the ocean sides of their grounding lines.
