Delaware Sea Grant’s slogan is “Science serving the Delaware Coast.” Much of the work done at Sea Grant focuses directly on working with coastal communities to improve their economies, their preparedness for coastal hazards, and their abilities to grow sustainably. For example, Delaware Sea Grant is actively pursuing oyster aquaculture in collaboration with Delaware oyster growers and the state of Delaware to establish a coastal market for farmed oysters.

The College of Earth, Ocean, and Environment (CEOE) at the University of Delaware also plays an important role in using research to help coastal communities adapt to a changing world, and often works with Delaware Sea Grant to reach out to local communities. Delaware Sea Grant and CEOE together conduct research on sea level rise and work with state and local representatives to help residents understand the potential impacts of sea level rise on coastal flooding and future storm impacts.

5 — World Soil Day – This day is aimed to celebrate the importance of soil as a critical component of the natural system and as a vital contributor to the human wellbeing. Head over to our SeaTalks page to learn about Greenwich Loam, the state soil of Delaware!

7 — First State – Delaware came by its nickname by becoming the first of the 13 original states to ratify the U.S. Constitution on this day in 1787.

11 — International Mountain Day – This day was established by the UN General Assembly in 2003 to encourage sustainable development in mountains. Although mountains may be the last thing anyone thinks about when thinking of Delaware, the northern part of the state is the start of the Appalachian Piedmont. Learn more about this fascinating geology on the Delaware Geological Survey's "virtual book," The Geology of Delaware.

21 — Winter Solstice – First day of winter. The shortest day of the year is marked by many ancient and modern seasonal traditions that celebrate the return of the sun and longer days.

25 — Christmas Day – In the spirit of this holiday, give back to the planet by recycling your tree into mulch.

31 — New Year’s Eve – A day for revelry and reflection. How will you resolve to care for the coast in 2018?
