    ** Focus Group #1: Identify challenges that women face in the workforce, and propose solutions to each of these that will allow for the gender gap to decrease and to remove the stigma associated with women in geosciences.

    ** Focus Group #2: Identify relationships between women, science, culture, and politics. Propose ways to strengthen these relationships in order to decrease the gender gap and/or stigma associated with women in science.

    ** Focus Group #3: Identify opportunities for women to act as leaders within the geoscience community. Propose areas of interest where female geoscientists can take on these leading roles.

    ** Focus Group #4: Examine the ways popular media and advertising portray women in science. Do you think these strategies attract women to science? How could outreach efforts be improved to reduce the gender gap?
