Hops are a species of vine, whose flowers are used in the beer-brewing process. It provides flavor to beer, and has several varieties. This variety is called Cascade.  

Wine-making grapes, like these Syrah (or Shiraz) grapes, require different growing conditions than grapes meant for eating. Cultivating wine grapes involves trying to concentrate sugars and encourage thicker skins, because these are what give wine its flavor. To do that, one of the most important factors to look for is the drainage of the soils.

Once harvested, hops are usually dried before adding to the brewing process. This variety is called Simcoe hops.

Growing wine grapes is a delicate balance between beneficial and excessive shading. Some shade is good to prevent heat-induced stress, but too much shading can lead to negative impacts.

To allow the grapevine to concentrate its resources more effectively, sometimes certain grapes are removed in a pruning process. This allows the remaining grapes to receive more of the plant’s energy and resources.

Geology plays a significant role in the wine and beer making process. Not only do the types of soils in which the hops and grapes are grown impact their flavor, but sometimes geology can also play a more direct role. Beer and wine are usually filtered before aging, and one of the more popular filtration materials is a mineral known as diatomite.

Ten minute samples from ichthyoplankton nets deployed near the bottom of the Missouri River.  Samples are sorted and searched for paddlefish and sturgeon free embryos.

The red is due to the presence of astaxanthin, a pigment in the cells.

The USGS R/V Kaho was Christened and commissioned on August 6, 2014, in Oswego, NY. The vessel was designed with state-of-the-art navigation and scientific capabilities, giving the USGS modern scientific resources for research into Lake Ontario’s coastal and deep-water ecosystems.
