Greeting MARMAM, please consider this email, not the one I sent before. Thanks! Greeting MARMAM, As researchers of Colombian Maritime Directorate, currently we are conducting a study to evaluate potential collision risk for five cetacean species with touristic vessels. We really appreciate your support as marine mammals specialists to complete a short survey (8 mins) and send me by *September 20*. Please find attached the survey as an excel file and its instructions in pdf. Let us clarify that we request your opinion as specialists based on your experience working with marine mammals anywhere, not specifically in Colombia. Please feel free to share this survey among your colleagues. We greatly appreciate your time and collaboration in our work. Thanks in advance, All the best, Dalia *Dalia C.
